That's some good quality cassette player right there. So many "sensors" and the mechanics look well built. Also, the belts are fine, too. Panasonic did a great job with this player. Fixed and ready to be used for many years to go. Congratulations!
Dude you've sold me on this unit! I just want to say that I love your videos. Everything you post I'm interested in or didn't know I was interested in! Thank you for making your vids!
I had this radio in the 90's - 1994. Sounded very good for being an all in one. Woman downstairs did not believe me when i told her it was a radio. She had complained nicely about the strong bass. I had her come upstairs and see for herself, she did and i had it at the level i listened at. Not super loud, she was amazed and said i expected big speakers and a big amplifier. Nope just a radio on my desk.
Thank you so much for making this video. I have one of these ghetto blasters, and it was given to me for xmas back in 1993. The tape decks haven't worked in fifteen years, but I could never bring myself to throwing out the stereo. I'm totally going to try cleaning it out, following your lead.
Sweet. I used to have the 680, and when it died, I bought the DT690. I still have the 690, but the CD player is dead. I miss this style of portable, that looked "normal" and not like some mutated insect or alien spaceship.
@@izzyyanuzzi954 Unfortunately, I am all the way down in California. I did however fix the CD player by finding a mechanism on ebay from the RX-DS17, which used the identical mechanism. Now, I still have to fix the motor control issue with the tape decks.
What a beauty! I have a similarly old stereo from Panasonic (SA-DH30 to be precise), and it still works great. Both tape decks are fully functional on it as well. Panasonic must've used some really good belts back in the days.
Not like the cheap-ass belts some lower-level brands used at the time - nowadays those would all be a sticky gooey mess that can take anywhere up to 5 hours to remove from pulleys and flywheels. I recently dealt with a Hitachi rig with this exact issue.
Thanks for this video. Bought two back in the day for family members and still have one unit. Love it and it sounds great. They were in the three hundred range if I remember correctly as the top of the line, big money back then.
i remember that singer, i was a big fan of his back in the 90's, he had a debut song called "my heart has a history". i used to have a real nice boombox like that, it even had surround sound with two extra surround speakers poking out of each side. i remember it weighed a ton though! especially when full of batteries
Thanks for sharing the knowledge. Bought one with only the CD and radio working cassettes we’re doing the same in as in your video. I did what you did step by step and they are now fully functional. Thanks again.
Glad to hear it was not just me having troubles cleaning switches. I have not done consumer electronics for years. You always take me back, sometimes to childhood when you have tubes or Germanium.
Watching the problems you fix here also takes me back to early high school... when the scary kids had smaller boom boxes it got loud. Sometimes kids would get ahold of the completely trashed school boom box and it was always funny when someone would have to dive across the room to stop it from eating their early 'gangsta pop-rap' music tape. You'd hear the treble start to fade down and then crinkling as it slowed down and someone would shout NOOOO! Of course some else would steal the same boom box from the AV closet and it would happen all over again!
I remember those days - the issues with school boomboxes is they were never serviced or cleaned which may explain why so many tapes got wrecked in them.
I used this for many years to teach ballroom dancing. The remote was great so could start and stop the music from the middle of the room. The sound was clear and loud enough to fill a ballroom or gymnasium. Thank you for the review.
My favourite type of electronics and my favourite service part on them ;) It is a pleasure for me to watch this video! The old belts are made from quality rubber that does not desintegrate like new ones.
Very good video of your repair. I had this unit from the early 90's until the 2000's, when the unit was in the sun in the car and the CD top distorted and I had some cassette problems, after which I did not repair it and disposed of it. It was a good unit and I have seen some offered on eBay. It also had Automatic Music Selection, AMS, which let one scan through the music and if one left a space between tunes, one could skip to the next tune.
I sold many of these Panasonic RXDT 680 and 690, and the smaller RXDS20... They sounded good for the price, had a digital tuner and a remote control, and apparently they were made to last. 30 years later, I was delighted when you rescued this one from dust. It's surprising the CD has not suffered (door switch, optic unit...), and the potentiometers seem to operate without too much noise! I remember clients complained about a missing power cord, untill Panasonic made a little sticker that said it was in the battery compartment...
This video encouraged me to check if my RX-DT680 had the same problem and it sure did while I thought it was acting up because of bad belts! In my case I also had to check the battery/AC power switch in the power connector because it was also corroded. Thank you!
Respect, this is my first radio that parents give it to me on birthday. And yes it sound is powerfull in these years. In my street i was coolest guy with this radio.
Takes me back to the early 90's when you play that easy listening music on that thing. My parents had something like it with the motorized volume in their bedroom b4 the cd players were cheap enough. Dad always played easy listening on it (still does on anything else), kinda ran it into the ground for me tho, lol.
g'day fella. been hanging around your channel for ages. Just wanted to say that i always dreamed back in the day of having one. The one thing I always found interesting about the upper-end Panasonic (coming close to Technics) was the use of M.A.S.H with their CD systems.
I have a Magnavox D8443 ghetto Blaster boombox that I am restoring. Got everything working except the cassette and the audio ins and outs. I have a few of those Maxell high grade tapes, they sound amazing. I used them back in the day for recording mix tapes during the late 90s when I first started downloading music off AOL and yes I also used these tapes in my cassette recorder for making random recordings.
i've worked on many of these.. CD deck is a common failure.. but man these were well made.. and sound fantastic.. the RX-CT990 is my favorite of the series mainly because it had a true AUX input
That's the exact model I have, with the pitch control for Deck 1, sadly it does not come with digital tape counter, just displays TAPE when playing tape but still does the job. I encoutered the same issue as 12voltvids with the oxidised tape detecting and some minor dry joint due to age but other than that plays great and eats all of the boomboxes made today :)
My parents had one of these when I was a kid. Super cool. The motorised volume and logic controls was fascinating, was by far the fanciest piece of audio equipment I'd seen at the time. Pretty sure these are from '96 or thereabouts.
Nice fix 12voltvids . And thank you for showing this wonderful piece of bom box . i read a subscribers are interesting to by it .And they have right. Because this is the best sounding bom box. I have Panasonic RX-CT 980 and i will recommended to views to bye one off this bomboxes . Again 12voltvids has you said in beginning this sounds amazing. Your videos are very enjoyable. And entertaining videos
I find that using a strip of P1500 or P2000 wet & dry sprayed with dioxit works on most switches. It's such a fine abrasive it works well without scratching the contacts. Nice job. It's rare to find such a nice boom box in such good condition.
That's a nice unit , I have the big brother RX-DT690 that i did a full restore on the cassette mechanisms new belts, and new take up reel gears (RDG5772ZC) they lose teeth. also have RX-DT75 cobra that i fixed the cd player and re-foamed the speakers. and a RX-DS20 that i fixed the bad gears in same part number as the RX-DT690. those Panasonics were the best built in the day.
Just got this same unit at a Goodwill for $20. CD player not working.... turned out I had to adjust the laser pickup current and also I found the Cd disk seat was pushed down slightly effecting the focus for the laser to read the disk. Fixed now and surprised how good the unit sounds!
So at least four of them got broken in 10 years? That's surprising, they used to be quite reliable even with heavy use, easily lasting 10+ years without failure.
I have the same unit purchased at the Wiz in 1991, The tape mechanism is the same one as used on some of the lower end Technics (although good decks) cassette decks of the time.
Thats the exact unit that was in my Son in laws garage at the rental house they lived in. It lived in a dusty dirty environment, yet still worked. The tape decks didn't work on that one eather. It stayed there when they moved.
I have been using my Panasonic products for 40,years and they are still working fine . I can't say the same for the Sony products I have. I had to fix them a few times. Panasonic were high quality products.
Every company has good and not so good products. My old Sony beta and cd player are over 40 years old and work perfectly. I have several Panasonic VCRs that were high end (ag1980 and agw1) which are beyond repair.
I know also the cassette transport mechanism. It uses the panasonic/technics ar300. A typical issue is a gear that gets missing teeth for playback /recording and also the tape sensor leaf switches that gets corroded or oxidised over time.
That's the exact model I own, I modified mine for a AUX input as after years of using dummy tape for inputting audio the tape mechanism's broke. I download a service manual with schematics and imputed line level at the graphic equalizer circuit. I use it every day at work, Great sounding stereo for its age.
I have this same unit. Both cassettes work, CD works. The tuner works, but presets do not, so it has to be manually tuned. Timed recording doesn't work either. These last two issues are most likely just the switches...we'll see. The S-bass knob doesn't have much effect, so I think it's not working right. Going to try to restore it fully. Fun project, though I have no idea what to do, so I'm counting on channels like yours to give me insights. Keep up the good work! If you know where I can get a schematic I'd love to know! Might come in handy trying to figure out the S-bass issue. You've gained a new subscriber.
@@adsbadsb9488 Thank you for the response. Moved recently and now have it set up and playing, as my other stereo is in storage temporarily. Haven't done much to it yet...too busy. The S bass works, though subtle, as you mentioned. Perhaps that's the way it is. Just used to a more dramatic effect I guess. I am still going to look for a schematic. I'll let you know if I find one.
My DT690 can be set up with 2 C-120s and the timer to record up to 4 hours off the radio while away, sort of like a VCR. Was great for catching broadcast live concerts and such.
I still have that exact same model in my mancave... Absolutely love it. Only thing is the CD player doesn't work all the time, sometimes it takes a while to play, other times it doesn't at all. Is there a way, like an attachment to make this use or connect to Bluetooth..?? Now that would be handy.
Tuner / amp almost always work. Best use now is for computer audio. Sound good & you can adj the audio in a natural way & easy way. Also cuts down on wires & clutter ! Used to get lots with double decks. Both decks would ave bad motors. Wear out the A deck then the B deck. LFOD !
I just got a hold of a 610 which is similar to what you working on there but a little further down the chain. My left cassette plays a little bit sluggish and the right one plays way too fast. Any suggestions? I was kind of hoping you would have to go to the belts on this so I could see how you access them.
i did nt know this unit had full logic controls panasonic technics makes amazing audio gear i ve had so many models of boomboxes tape decks over the years !
Purchased this model for $10 + $16 shipping with remote control and operation manual. CD still not working and tapedecks had exactly the same issue described in your video! Common issue? Don't take it apart yet, however fix the tapedecks on the outside by dipping (not spraying) some wd40 onto the contacts and wiggle it. It take some time to do its work, you don't need to sandpaper the contacts., take your time. Tapedecks only play tapes in one direction, reverse direction. Takeup wheel in forward mode (eat tape mode) does not have to power to wind the takeup reel. That is weird, because it is a gear controlled - see 17:45. The CD, the laser unit tries to focus (don't move) and motor doesn't spin - no disc message. I used my phone's camera to spot some light activity but cannot see anything. Bad laser? It is a beautiful device when cleaned and sound is decent. The downside is that this model doesn't have an AUX input however have seen some mods already. You make great videos maybe you have to do some repair and mods videos.
My panasonic left tape deck would not play, intermittently would FF but does rewind. I followed this video of cleaning the contacts but no luck. Any help would be appreciated. Thank you.
I just bought one of these two not too long ago at a yard sale how do I separate the speakers from the main component I see the release latch but nothing's doing anything to snap them apart or slide front-to-back is there something I'm doing wrong
Hello. I really like your video tutorials about repairing different staff. One can learn so much from them! I was wondering whether you happened to come across Portable Stereo Panasonic RX-ED77, widely known as Cobra. Two decks are completely unresponsive when I press the play, rewind or fast forward buttons. I once tried to change the belts but I'm afraid I did something wrong. I'm also thinking that main gear (rdk0026) can be the reason why it's not working. Can you advise something?
I have an old Panasonic I want my kid to be able to use - and the tape deck was working well, but now it simply won't close when I have a tape in it. It closes perfectly and works fine otherwise, but just every time I try and close the deck with a tape in it, I can feel something resisting at the bottom. Any idea what it could be?
Hi there, I have this RXDT680 but my CD is broken. I bought a new cd lens but it doesn't read CD's. Please can you help me figuring out where can I find the audio in for CD so I can use a portable cd player on it?. Thanks in advance for your advice
I have a Panasonic RX-FM40 XBS Extra Bass System. The play button is stuck and I can’t figure out how to fix it. Do you have a video or any advice on how to fix the play button?
I actually learned something today and am anxious to find one of these (or one that is near to it)! THANK you for making my day a learning day (inhouse most of the day because of the virus). Maybe you'll have one that has CD problems.
Hi there, Sir. After watching this very informative video, it is more than clear to me that you know 100% more about this ‘boombox’ & or any other one, than I ever will. So in that regard, I have just one question regarding this exact same model. On the rear of mine, because one of the spring speaker terminals clip push release connectors is ‘out of it’s socket’ (the red on, to be exact) the red/white speaker wire that goes into it does not stay in place. Thus making the right speaker cut in & out. So I was wondering might you have any suggestions as to how I could temporarily prevent that from happening. And or would I have to replace the entire terminal pertaining to the right speaker. If so, any idea of what kind of cost I would be looking at to do just that. The cost of said terminal & the repair, I mean. Any help & or tips would be greatly appreciated. A great weekend to you & yours. Cheers!!!
Great video! My mother was given a Panasonic RX-ED77 ghetto blaster which is having the same problem with the dual cassette. I cleaned the contacts with cleaner but it's still doing the same thing. I was wondering if the plastic covers on the switches can be easily removed if the tape doors are still in place? I'm not sure if you are familiar with the RX-ED77, but the tape deck is hidden underneath a pop-up control panel on the top of said unit and to take the doors off pretty much requires ripping the whole unit apart just to properly clean the switches. Also ... Any recommendations on where to get belts for cassette players online? Cheers (and just subscribed!) from Canada!
Yes this one is a good one I got it for free and will probably hang on to it because it's a good unit has good sound. They don't make them like this anymore even just to use it as a radio. The tape decks don't do anything for me because I don't use cassettes but the CD player is nice and having auxiliary input lets me plug in any streaming devices and take advantage of those nice speakers and bi-amp circuit
@@12voltvids yep mine has no aux input its the RXDT675 so ill have to hack into it and wire in a 2 pole switch in line of the tape preamp chip and if i do all that mess ill bucktooth 4.0 board and upgrade amp with a programmable Frequency deal but lol oh man tweak the heck out of it most likely .or stream via fm-transmitter for now is Z solution
Do you have a video of the back? The amps? I was always curious because the 4 PDS systems were much heavier then the non pds versions. Didn’t know if it was the speakers or the amp as well that added to the weight.
Hi I have a JVC HR-S9500 SVHS VCR as soon as I insert a tape it chews it and ejects the tape, it makes a whirring noise once a tape is inserted, do you know what maybe the cause.
Hello, great video you have here. I have an RX-CT990, it is the same but it does not have a CD. I have to do the same job, remove the front part, clean the heads and lubricate it. I don't have a screwdriver that long and I have to buy one online. Can you tell me the measurement, the caliber of the screwdriver tip that goes there. Thank you very much for your help. Greetings
Really need help. My camcorder's (ccd-trv128) viewfinder is EXTREMELY loose. I wish to know what screws I should tighten up. I'm worried that if I dismantle the device I'll break it.
I have a similar unit made by Sony. Currently in what i call deep storage. Foil sealed bag with desiccant bags. In theory it could sit around like that for years and years.
My RX DT670, i can hear a motor running whenever it is plugged in. Even if the power button is shut off. Normal? What is going on? The unit works fine. Thanks
I have the same unit and in working... Unfortunately it has been put to standby mode and is not getting off it... Can you help how to undo that or remove from standby mode
I'm having the same problem with my old portable stereo. It's more than 25 years old and just sits around because of the detector switch problem. I've always found the Panasonic portables had the best sound but the RXDT707 beats them all. If I could just get it apart I might be able to clean the switches.
First time ever seeing someone legitametly clean and repair a cassette deck . Nice work
That's some good quality cassette player right there. So many "sensors" and the mechanics look well built. Also, the belts are fine, too. Panasonic did a great job with this player.
Fixed and ready to be used for many years to go. Congratulations!
This one is staying in my collection. It is a dam good unit.
@@12voltvids could you show how to add bluetooth to RX-DT690?
This system has amazing sound for it’s time and size. Digital, Dual auto reverse.... oh my days!!! The features back in the day.
Great sound on your machine there. I'm envious. We got this to replace our old one from the late '80s. The Panasonics were so well-built.
Thats a great blaster! I remember my mom buying the low end model that had the single cassette and no CD, same bi amp and speakers.

I have this same unit. Both cassettes work, CD works. The tuner works, but presets do not, so it has to be manually tuned. Timed recording doesn't work either. These last two issues are most likely just the switches...we'll see. The S-bass knob doesn't have much effect, so I think it's not working right. Going to try to restore it fully. Fun project, though I have no idea what to do, so I'm counting on channels like yours to give me insights. Keep up the good work! If you know where I can get a schematic I'd love to know! Might come in handy trying to figure out the S-bass issue. You've gained a new subscriber.
@@adsbadsb9488 Thank you for the response. Moved recently and now have it set up and playing, as my other stereo is in storage temporarily. Haven't done much to it yet...too busy. The S bass works, though subtle, as you mentioned. Perhaps that's the way it is. Just used to a more dramatic effect I guess. I am still going to look for a schematic. I'll let you know if I find one.
@@adsbadsb9488 got the service manual…thank you! That will be ver useful! I didn’t see the “mod idea.”
I have one of these very similar. They are great for a portable unit.
My DT690 can be set up with 2 C-120s and the timer to record up to 4 hours off the radio while away, sort of like a VCR. Was great for catching broadcast live concerts and such.
I had the separate components when I was a teenager given them by my neighbor
I have one exactly the same. I bought it brand new when I was 16 back in 1992.
Well, I got to say besides from the dust build up and some cleaning. This boombox is in fantastic shape and function decently all things considered.
I'll show it off after I clean it up
I still have that exact same model in my mancave...
Absolutely love it.
Only thing is the CD player doesn't work all the time, sometimes it takes a while to play, other times it doesn't at all.
Is there a way, like an attachment to make this use or connect to Bluetooth..??
Now that would be handy.
Tuner / amp almost always work. Best use now is for computer audio. Sound good & you can
adj the audio in a natural way & easy way. Also cuts down on wires & clutter ! Used to get lots with double
decks. Both decks would ave bad motors. Wear out the A deck then the B deck.
LFOD !
I just got a hold of a 610 which is similar to what you working on there but a little further down the chain. My left cassette plays a little bit sluggish and the right one plays way too fast. Any suggestions? I was kind of hoping you would have to go to the belts on this so I could see how you access them.
It's got decent tape decks. None of that mechanical auto-stop where a lever gets pushed if the tape gets tight when it reaches the end.
i did nt know this unit had full logic controls panasonic technics makes amazing audio gear i ve had so many models of boomboxes tape decks over the years !
Its in mint condition. It would be awesome to see more repairs of this boombox soon.
It is in pretty good condition alright
Purchased this model for $10 + $16 shipping with remote control and operation manual. CD still not working and tapedecks had exactly the same issue described in your video! Common issue? Don't take it apart yet, however fix the tapedecks on the outside by dipping (not spraying) some wd40 onto the contacts and wiggle it. It take some time to do its work, you don't need to sandpaper the contacts., take your time. Tapedecks only play tapes in one direction, reverse direction. Takeup wheel in forward mode (eat tape mode) does not have to power to wind the takeup reel. That is weird, because it is a gear controlled - see 17:45.
The CD, the laser unit tries to focus (don't move) and motor doesn't spin - no disc message. I used my phone's camera to spot some light activity but cannot see anything. Bad laser?
It is a beautiful device when cleaned and sound is decent. The downside is that this model doesn't have an AUX input however have seen some mods already. You make great videos maybe you have to do some repair and mods videos.
I've got the slimmer RX-E300 model. It's still working fine except for the tape playback gear is broken. So it only works in reverse.
My panasonic left tape deck would not play, intermittently would FF but does rewind. I followed this video of cleaning the contacts but no luck. Any help would be appreciated. Thank you.
I just bought one of these two not too long ago at a yard sale how do I separate the speakers from the main component I see the release latch but nothing's doing anything to snap them apart or slide front-to-back is there something I'm doing wrong
I just got this exact player from a garage sale and have the exact problem. Everything else works fine.
I have a RX-DS660 panasonic boom box that I got on Ebay and it works great.
thanks for this video about the switches thank you
Hello. I really like your video tutorials about repairing different staff. One can learn so much from them! I was wondering whether you happened to come across Portable Stereo Panasonic RX-ED77, widely known as Cobra. Two decks are completely unresponsive when I press the play, rewind or fast forward buttons. I once tried to change the belts but I'm afraid I did something wrong. I'm also thinking that main gear (rdk0026) can be the reason why it's not working. Can you advise something?
Hello. Do I need a special adapter for my Panasonic RX-DT600 here in the USA?
I have an old Panasonic I want my kid to be able to use - and the tape deck was working well, but now it simply won't close when I have a tape in it. It closes perfectly and works fine otherwise, but just every time I try and close the deck with a tape in it, I can feel something resisting at the bottom. Any idea what it could be?
Hi there, I have this RXDT680 but my CD is broken. I bought a new cd lens but it doesn't read CD's. Please can you help me figuring out where can I find the audio in for CD so I can use a portable cd player on it?. Thanks in advance for your advice
I have a Panasonic RX-FM40 XBS Extra Bass System. The play button is stuck and I can’t figure out how to fix it. Do you have a video or any advice on how to fix the play button?
I actually learned something today and am anxious to find one of these (or one that is near to it)! THANK you for making my day a learning day (inhouse most of the day because of the virus). Maybe you'll have one that has CD problems.
Very nice radio
Hi there, Sir. After watching this very informative video, it is more than clear to me that you know 100% more about this ‘boombox’ & or any other one, than I ever will. So in that regard, I have just one question regarding this exact same model. On the rear of mine, because one of the spring speaker terminals clip push release connectors is ‘out of it’s socket’ (the red on, to be exact) the red/white speaker wire that goes into it does not stay in place. Thus making the right speaker cut in & out. So I was wondering might you have any suggestions as to how I could temporarily prevent that from happening. And or would I have to replace the entire terminal pertaining to the right speaker. If so, any idea of what kind of cost I would be looking at to do just that. The cost of said terminal & the repair, I mean. Any help & or tips would be greatly appreciated. A great weekend to you & yours.
Cheers!!!
I use to sell these as a kid for my Dads little electronic shop in the late mid-late 90s
Reminds me of my Technics SU-X930 with the cassette decks.
I couldn't afford one when they came out. In 2021 I got a RX-DT690. I will add bluetooth option in it.
Great video! My mother was given a Panasonic RX-ED77 ghetto blaster which is having the same problem with the dual cassette. I cleaned the contacts with cleaner but it's still doing the same thing. I was wondering if the plastic covers on the switches can be easily removed if the tape doors are still in place? I'm not sure if you are familiar with the RX-ED77, but the tape deck is hidden underneath a pop-up control panel on the top of said unit and to take the doors off pretty much requires ripping the whole unit apart just to properly clean the switches.
Also ... Any recommendations on where to get belts for cassette players online?
Cheers (and just subscribed!) from Canada!
I prefer the graphic equalizers over preset equalizations. Nice "vintage" unit.
i just got a rxdt675 very similar just no darn aux but ill fix that to me is a must have.i would love to buy that model you have their to
Yes this one is a good one I got it for free and will probably hang on to it because it's a good unit has good sound. They don't make them like this anymore even just to use it as a radio. The tape decks don't do anything for me because I don't use cassettes but the CD player is nice and having auxiliary input lets me plug in any streaming devices and take advantage of those nice speakers and bi-amp circuit
@@12voltvids yep mine has no aux input its the RXDT675 so ill have to hack into it and wire in a 2 pole switch in line of the tape preamp chip and if i do all that mess ill bucktooth 4.0 board and upgrade amp with a programmable Frequency deal but lol oh man tweak the heck out of it most likely .or stream via fm-transmitter for now is Z solution
I don't have the amp but i have the left channel one and connecting it to an ext amp it sounds super good
Do you have a video of the back? The amps? I was always curious because the 4 PDS systems were much heavier then the non pds versions. Didn’t know if it was the speakers or the amp as well that added to the weight.
It is a bi amplified. 4 amps. 2 for woofers and 2 for tweets
Hi I have a JVC HR-S9500 SVHS VCR as soon as I insert a tape it chews it and ejects the tape, it makes a whirring noise once a tape is inserted, do you know what maybe the cause.
Hello, great video you have here.
I have an RX-CT990, it is the same but it does not have a CD.
I have to do the same job, remove the front part, clean the heads and lubricate it.
I don't have a screwdriver that long and I have to buy one online.
Can you tell me the measurement, the caliber of the screwdriver tip that goes there.
Thank you very much for your help.
Greetings
I would love to have this radio. Reminds me of the one Dad had. Beautiful machine.
Really need help. My camcorder's (ccd-trv128) viewfinder is EXTREMELY loose. I wish to know what screws I should tighten up. I'm worried that if I dismantle the device I'll break it.
I have a similar unit made by Sony. Currently in what i call deep storage. Foil sealed bag with desiccant bags. In theory it could sit around like that for years and years.
My RX DT670, i can hear a motor running whenever it is plugged in. Even if the power button is shut off. Normal? What is going on? The unit works fine. Thanks
my amplifier on my left channel started to crap out...any way of fixing her ?
I have the same unit and in working... Unfortunately it has been put to standby mode and is not getting off it... Can you help how to undo that or remove from standby mode
I'm having the same problem with my old portable stereo. It's more than 25 years old and just sits around because of the detector switch problem.
I've always found the Panasonic portables had the best sound but the RXDT707 beats them all.
If I could just get it apart I might be able to clean the switches.
