- The Sony/Tascam DTRS format is a professional 8-track digital audio recording onto Hi8 tape. Models include the Tascam DA-88 (which the format is often known as), DA-98HR, DA-38, DA-78HR, DS-D98 and Sony PCM800. These machines can damage tapes due to incorrect back tension which is often caused by a lubrication issue. Let's fix a DA-98HR and check over a DA-88 and PCM800.

Oh My Lord, I just completed two successful repairs to two individual PCM800's. Both function smoothly once again, neither are munching tapes anymore and both have smooth wheels and oiled back tensioners and sound like new again. Thank you so much for you super valuable videos. I think what I learned from you the most is the deliberate moves. Every move you do in your videos is very much deliberate in my eyes. Nothing rushed and never skipped any unforeseen issues to resolve along the way. I'll be sure to visit your Patreon at the beginning of the month when I'm flush. Now I have access to 26 Masters I've created of original music dating back to 1997 thru 2019. No kidding... Thank you again Sir.
Now I think I should try to figure out how to set up both working machine to go from an 8 track studio to a 16 track studio. Added benefit is staying in a format that uses a mixing board to work with. So much easier that a DAW and all that learning curve. This works for me.
Once again Sir, I do thank you sincerely.
Shane
Yes, a real time tactile mixing board and no latency issues on overdubs. It boggles my mind that everyone waves off latency issues with every DAW out there.
i use to fix these and adats back in my days lol it all started with me fixing vcr's o would find in the trash growing up in brooklyn east nyc in the 80s lol
Sorry it's been a over two weeks since my last video. I have several more partly recorded but am awaiting spares in order to complete.
Very nice machines, this digital audio multitrackers.
I'm in the business, but never had the opportunity to play with this kind of audio studio pro gear.
Inside, the deck, it's like a Hi8. Oh, man, nostalgia strikes when I hear those noises... My first Hi8 was an EV-S1000E, back in 91.
As always, a very interesting video.
Cheers 🇵🇹
The back tension servo (it's a mechanical servo to regulate the back tension) is a common problem. The tension servo is much the same in most any VCR. I have had 3 DA-88s with the back tension arm frozen in place. I did what you did, remove it, clean and re-lubricate with a very small amount of light oil. The DA-88 is a very similar transport to the DA-38. It's interesting to see how similar the Sony 8 track machine PCM-800 is to the DA-88.
The PCM-800 mainly differs in the connectors, which are more analogue based.
Thanks
I don’t miss my DA 88’s at all. They broke down a lot.
Enjoying the Techmoan mug in the background.
Hi, my friend! I have had one of these for over 5 years and still haven't fixed it. The time is now! Thanks!
Yes, give it a go. Start by taking a look to see if the back tension arm is sticking in the wrong place.

Of course! It will be the second item that I will check. The first item is the activation of a channel that is not working. I have already tried moving the board replacing some audio ics and nothing. Do you have an idea?But I still haven't given up on this one.
Great channel and content, I have a few older VHS and Beta machines here.
Glad you like what I do. It's kind of a mix of 12voltvids, Techmoan, Play with junk, Technology Connections, shango066 and similar, but I don't think I can quite compare with any of those!
@@video99couk They're no better than you, and you know more than some of them. Only differences is they have more subscribers..... so far.
My 424mk3 Portastudio does the T A S C A M scrolling over the meters thing too!
Great video, thanks for sharing this
Scott is going to be a heartbreaker, I feel sorry for all the girls who will have crushes on him. However he will make a great engineer in the future. We all look forward to our kids success.
hello do you know if the cable for the RC 848 used to control the Tascam DA38 & 88 is a straight DB 15 Male/Female or is it a special cable thanks in advance
I'm not familiar with the RC848, but if it connects to the same port as the Tascam HD24 (and I think it does, via the master and slave connectors) then it's a straight through cable. What isn't straight through is the DB25 cable used for digital audio output, that's a much harder cable to source (though I did get one).
I have 2 of the da88, one has a clock error and then err 11 and the other has an err 01. Any ideas on this ? I’ve tried the 3v battery on both motors and they work well. Anyone in the uk
Could look at these ?
I’ve literally just opened the da88 with the err 11 code and the arm that you cleaned out well my one is stiff and seems really sticky
update : i have managed to free the arm and its springing back now but i still have the err 11
Oh, just use tweezers 23:04 LOL
I did not know these machines existed , very cool multitracker !
A few years back I was blissfully unaware of these machines too. That's the joy of this job, I'm always getting to play with unusual and cool stuff.
Well done. I don’t know if I’m inspired enough to crack open all of my idle DA38 machines yet, but I always suspected there might be a common lube point responsible for the majority of tape transport foul ups. My linked machines would also drop in and out of sync periodically, I could see where this might be a root cause of that issue as well.
It's certainly worth having a look for this since it's reasonably easy to spot once you have the lid off.
Have you ever had an S-Err-41? It's when Fast Wind (FF/RW) fails to get up to speed. I read that it's where a solenoid fails to engage, could be a bad solder joint, or a cracked lever of some sort. My machine works perfectly except for this one issue.
Not had that one. At least it's not a total show stopper since you can wind tapes in another deck.
Another interesting problem solved!
Any recommendation on where to look for a pinch roller for the tascam Da 88 would be appreciated. 🙏. Love your videos and your studio, keep up the good work.
I don't know, but would suggest you look at Eddie Ciletti's web site: www.tangible-technology.com/
He may be able to advise on this.
Hi friend, y name is Marco, i'm from Brasil and i'd like to know How do you connect an analogic mixer (Behringer 3242MX) to a DA98HR..thank you
That's a bit out of my area of expertise. The video I link to: czcams.com/video/5BA_7xgMB6c/video.html
Is by Magic Spiral, who might be better able to make suggestions about that.
it is explained in the user manual of the mixer
Thank you for another interesting video! Though, may I ask that you not use the zoom in / zoom out effect this often in the future? I found it very annoying in the middle part of the video where it had been applied to almost every scene...
I was having a bit of trouble with DaVinci Resolve. I needed to use the zoom function for a couple of clips, but then it kept "popping up" on other clips where I didn't really want it. So I tried to set the zoom windows to do as little zooming around as I could. I generally don't use this feature I will try to avoid it in the future, except where absolutely unavoidable.
Hi and thanks for posting this video. I´ve just got a da-88 which is showing Err 01 immediately after start, and when you push the tape in, there is no movement trying to grab the tape inside. what should i do first to start the review? I can remove the whole transport chasis and test if engine is working for ex.?? at first glance it appear not to be any damaged part, The Da-88 was always under original owner´s hands till now. I removed the cover and everything appear to be in excellent conditions. If you are able to help online, i can pay for that service. Thanks in advance.
i have 2 sony pcm-800's and they have an error S-Err 11 and the tape stays stuck in de player. any idea
It could be caused by the same fault as I cover in this video. You need to look at what happens when you put in a tape and eject it. Make sure the arm on the left is free to move and not sticking as it was in the machine I repair here.
I have exactly the same issue with my DA98, but also, the guide on the right (by the pinch roller) is sticky. I can’t see how to easily get this guide out, as the mode switch sits above it ! and this is where it starts to get a bit fiddly, especially without the manual...
You really need to get the guide out to get some lubrication on it? I can't quite picture which one it is but I would hope that you can lubricate it without totally extracting it. Perhaps contact Eddie (www.tangible-technology.com/), he knows these decks very well.
video99.co.uk I have tried working in some thin oil, but no luck, it’s still sticky. In the past, with other kit like the Sony dats, I have removed the guide, cleaned out the old grease with alcohol, applied some thin oil, and jobs a good un. But on this da98, it looks a mission to get the guides out, especially the R/H guide, but I will take a closer look at the weekend,. Currently have a laserdisc machine it bits !
Hi , what is your contact details for servicing this model. Thx
Hello Colin! Thanks for a video. I bloody love your English, especially combined with an ineresting repair on screen. Could you please clarify if it is safe to touch metal tensioner surface (the tape contact area) with a metal tool (screwdriver)? As for me it should be perfectly polished to prevent any possible mechanical influence on tape and contact, the way you did it on video, could cause micro scratches on metal sirface. So it's better to use either your finger (as you did either) or plastic tools.
I suppose a plastic tool might have been better, but I don't see this as a finely finished component in the same way as the lower drum is.
video99.co.uk video99.co.uk Well, it directly contacts the tape (does it?) If yes, any dent or micron-sized sharp metal "tooth" created by another metal object could play badly. Also, let me assume, as for tapes mechanical nature all touching surfaces through the recording mechanism should be approximately equally finely finished.
Hi
Can I have the names of the tools to remove the star lock washers ? Thanks
I think you are referring to the split washers on the back tension band? They can be removed with a bit of fiddling about with a small flat bladed screwdriver.
When you say "To be careful, make sure this is powered down before you do this", are you saying to discharge the filter capacitors or merely be sure the unit is unplugged from the wall socket?
Just unplugged, because the power switch could arc to the metalwork. No need to discharge PSU capacitors.
@@video99couk Thanks for the reply. I did as you stated regarding unplugging the machine, then went forward with the process of removing the carriage and its case to access the sticky guide.Just as the issue was in your video. I'm 99% sure I didn't cause any added damages in the work I performed. Everything looked as though the service was concluded successfully. Just so you are aware, I had your video on loop the whole time playing along, as I wore headphones on so to not miss anything, especially after the 3 and 4th time play through. Funny...
But. after everything was all said and done, I plugged in a Hi8 tape, the carriage accepted it the first time but would reel the tape out to the head. So I ejected it and attempted to input the tape in a second time. This time it would bring the tape in as it normally does. Then came the error message S-err 11 with the ABS light on and the warning light blinking.
The Sony PCM800 is important to me because I've used this deck and another same deck before this one to record 26 CDs of my own music. This deck is what is needed to play all my master tracks. This is my baby, you could say.
Any thoughts would be of such value to me Sir.
Spell Issues with the statement above. The tape never engaged to the head when inserted at the first attempt after the service to the guide was completed. I attempted a second time which initiated the error message
Hai sir DTRS PLAYER IS AVAILABLE IN INDIA RIGHT KNOW
Well done :-D
Sounds like the manufacturer used a different lubricant than other manufacturers of similar devices.
I've never seen a gungey tension arm on vcrs, but the felt band has caused minor problems like a jittering picture on playback or squeeking, All due to the pad being bone dry and not a smooth slippage.
A tiny dot of oil on the pad just allows a smoother slip.
I have had vcr's drive me mad with the tape riding up the guides/pinch roller, often the roller is the culpret.
That's it!, you have lost your job to a younger man ha ha :-D
I've known the felt completely fall off the back tension band too. I was concerned about possible pinch roller failure, but the other big cause of tape riding is a lack of back tension. A new pinch roller could be quite hard to source so I'm glad it wasn't the problem here. I've seen tape riding problems on the Sony EV-S9000E Hi8 deck also caused by a lack of back tension (when supply spool has been replaced) and also on an Akai open reel tape deck.
HA HA i find this funny my sister has a boy of 9 if i was training him she do her nut big time she's got a thing about tec A/V gear i was dealing it big time lot of rare gear
i have 7 da99 need of re capon the pcb under tranport get them young ace plan yes 240v down the side very bad
i have a EMI BTR4 transport green it's heavy 1/8 tape real time recording for cassette i have a otari DP2700 you get a super high out put recording
pete someone who had a talking book died sometime ago i had a video on youtube i pulled it was getting alot of emails 100's of them a week
this was when cassette crazy was very high small runs of band's there's a min run you see i for get what it is there is a master the cassette's are copyed of
loop tape or computer audio loop
It would have been a good idea if you were to first, take some Q-tips a.k.a. cotton swabs. And some, preferably, Freon. If you can still get your hands on a pint. Or some 91% isopropyl alcohol. And cleanup the bloody tape path first. Swab down the rubber pinch roller as you secure it. With a small screwdriver on top. And cleaned the gunk off that rubber tire. I mean, tyre. Because I'm old and tired. Of watching people not cleanup an old transport first. Before you stick a tape in.
And when you first stick one of those tapes in. You don't hit play. That is incorrect to do. So don't do that. No.
Note you first hit the fast-forward button.. And you wind that tape all the way through to the end. While that's flying along. You can open yourself up another pint bottle and pour some Guinness. Once you have consumed your Guinness. The tape will have already gotten to the end. And automatically rewind back to the beginning. Isn't that amazing? What will they think of next? I wish I could say this in your British accent. But I'm just a dumb ass Yankee. That worked as a managerial person. For one of the most famous tape recorder manufacturers in the world.
So I got three DA-88's and all the options. For a scant, $15,000 +. And they nearly put me out of business. They were not built well. They are not ready for professional use. The transports are no different. Then one of their $50 8 mm video recorders you would get at a big box store. I mean they were awful. It was fraud! Ain't nothing professional about said 8 mm transport. In a nearly $4000 US 1993 money, recorder each. And 800+ dollars for the SMPTE cards. An 800+ dollars for the big remote. And $500 for the remote meter package. And I had the only 40 foot remote control cable TASCAM ever sold. For the DA-88's. Because not all of them would work for everyone. Mine worked great.. But the recorders didn't last worth crap.
It was said something like 15,000 hours mean time between failures. The heads blew at 150 hours. That's not 15,000. That's not even 1500. That's 150 hours. I kept on shipping the machines back under warranty. They kept on shipping machines back to me. That wouldn't work out-of-the-box. I would call them on the phone and scream. They would send me brand-new machines. I've had nine.
Now as far as they sounded, when they work. Original only at 16-bit, 44.1 or 48 kHz. I used to hit the level hard. Peak lights would flash. I never heard any clipping. And in looking at its waveforms on the computer after 1996. I saw no clipping. If they clipped. They clipped softly. Without any loud over load clicking. Never. In that respect they sounded great. Nice and fat and full and smooth. But the transports were total crap. Just the worst disappointment. And there ain't no retrofits.
Secondarily. There is a little calling sized computers style lithium battery inside. That stores all of your settings. Even when the machine is turned off and unplugged for long periods of time. But after 10 years. Those batteries fail. That was 2003.
It looks like it should be easy to pop those batteries out and popped a new one in. Don't even try. You will destroy your machine if you do. This is a no-win situation. The batteries are soldered to the circuit board. Soldered so well. I couldn't even pop them off free. And trying to replace it I think would've been a pure disaster. And the damned machine knows it ain't got no battery. But it will still function. Don't expected to remember anything you set. It will just keep defaulting back to factory defaults. Turn it off and all of your settings are gone. And I don't know about you folks. Each channel has its own adjustable delay time. From going forward in time approximately 20 ms. To delaying its output to over 100 ms. And there's some pretty cool things you can do with that feature. I found it incredibly useful. Delay your snare drum by 2 ms. Just your snare drum. And listen how that changes a song. It's a night and day difference. Or let's say you want to put 30 ms of delay on your room MIC's. Because you don't have a big room. Adding 30 ms of delay gives you a much bigger room. Right out of the recorder.
And you should've had a good Handy Mag demagnetizer. And you should have thoroughly gone over everything inside that 8 mm transport.
I mean where the hell did you get your schooling? I got mine from Ampex and 3M and MCI. And oh by the way. I was the Quality Control Manager for another little-known tape recorder company by the name of Scully. And I found this TASCAM 8 mm transport appalling awful. A total rip off.
It should have been manufactured with a diecast frame. That is unbending. This thing is made from thin little aluminum alloy pieces of sheet metal. You can bend with your fingertips. And when it's in a rack and you are driving down the road. It turns your transport into a nice hamburger soufflé. And it was in a padded rack cabinet mounted as per, TASCAM's recommendations. Whoops. That didn't work out very well.
These were fun when they were new and worked good. Once I finally got the last three brand-new machines of the nine. Those heads lasted 850 hours before they blew.. They should have lasted 10,000 hours. And it only cost $600 to get them fixed. 10 years ago. So figure that times 2 now. If you can find any new heads? They are tiny little ferrite chips. Smaller than a human hair. I'm sure you won't have any problems finding those LOL.
I have hundreds of multitrack's I have never archived yet from those suckers. And I don't think they will ever play again. I'm told they won't. Masters from the 1990s and the double oughts. Major fucking chart topping groups all live. All through Neve and Sphere. All 24 track sets meaning, 3 tapes each. And they all have to synchronize. I'm going to have fun with that. (No I won't).
Or maybe they will just be lost through time? They were awesome tracks. Never time to get to that archive project. Before now when it may be too late. Oh well. I had a cool career for a while. Like 50 years. Yeah 50. And 30 was a big diesel truck recording big-time Bands, live. Many with multi-camera broadcast grade video. Also from my big diesel truck secondary video control room. Yeah that's a big truck. And then there is the rear machine room and storage with distribution amplifiers and scads of power supplies. It's Sound City on wheels only better. Yes better. Because Rupert Neve told me so. And why shouldn't I believe him? He built my audio console. And it's better than Dave's I'm happy to report. And 100% full custom for NBC-TV.
And so I got to test drive my audio console for 12 years. Before I purchased it. I figured this would do.

The decks had already been cleaned with IPA when I first got them, but wasn't worth talking about. I believe all three are very low mileage. You'll see me IPA various tape paths on my other videos though. I'm cautious with the demagnetiser, not all formats appreciate it. Get a demagnetiser near a DCC format machine and you've destroyed it in an instant, so it's not something I use out of hand. But I do often use that on my Ferrograph open reel tape deck. As for my "schooling", I'm an electronic engineer who worked in the semiconductor industry for some 25 years. So we have different backgrounds and different perspectives. As you will see from my channel, I can repair audio/video equipment down to component level, a skill which is increasingly rare these days.
