It's great to see a video not 'sugar coated' but an honest approach to issues and repair. Thanks.
Your welcome and thank you very much for your kind words.
I watch several different vintage audio restoration channels and love them all but yours is definitely the most entertaining.
Thank you so much for the kind words and for watching.
Beauty, one of the best
She's a beast. Thanks for watching.
For brittle plastic - try baking soda and crazy glue. Works great for striped out plastic screw holes.
Thanks for sharing.
That's funny. I worked on copiers and we got a bulletin about using baking soda and super glue to repair certain plastics.
So excited when I see you have a new video. Fun and and inspiring to listen to, and great to see amazing gems like these resurrected! Thanks again!
Thank you so much!
The Master is in the house! Always a treat!
Thank you so much for watching!
I love this. I repair and restore vintage synthesizers and audio effect processors and the like. It's always amazing watching people debug electronics. I've been doing it for years, but I always pick up new tricks by watching people like you.
Excellent diagnosis video, Chris. Please keep them coming.
Don, thanks as always.
Nice. Just got my 2325 back from my technician so glad to finally find someone who knows what he is doing around vintage receiver. 😊
Fantastic work ! Now that’s what I call a hobbyist and enthusiast ! Keep up the wonderful work !!! Immy
Thank you very much!
Terrific job, Chris! Now you'll have to track down that snazzy wooden case for the 2500 to match your other 2500.
Thank you. I was lucky that the first one included the case. The cases by themselves are going for more then I'd like to pay.
@@vintageaudioaddict No kidding!
Thanks for the video.
You are welcome!
2 PLASTIC teaspoons or tablespoon measuring spoons work great for removing stubborn knobs without scratching the surface.
Thanks for sharing. I think this one would have broke the spoons, LOL.
@@vintageaudioaddict I have a 2245 that had that problem. Gotta use ones with hard plastic and a decent thickness. They are part of my workbench now!
Bicycle tire levers have helped me on stubborn knobs
Love your vids, thx a lot, and again: greetings from germany. 👍🙏
Greetings from the USA. Glad you like them! Thanks for watching.
OMG I laughed so hard when I saw those calculations !
Ya, It took a lot of figuring, lol. Thanks for watching.
Thanks for the enlightening vid. Love the shirt!!😂
Love my 2275 still going strong.
Gorgeous equipment. Ive got a modest marantz 1550. Love that little beast
The older gear was built so well. Your 1550 is engineered and built to the same standards are this 2500. Enjoy!
@@vintageaudioaddict i do. Im down to 3 vintage receivers currently. The marantz, a sony str v5, and a sansui 8080db. But my current setup has a modest kenwood preamp and the mighty Harmon Kardon Citation 16. What a great amp. Dead quiet, low noise floor except for the occasional noisy vinyl. Just wow. Thanks again for your content
Glad you are back
Yup, still kicking. I work on editing the video's more then I work on the equipment.
@@vintageaudioaddict i believe it! Takes some time. We appreciate it. Cheers!!
Nice work man! 🍻
Thank you! Cheers!
Love watching your videos 👍
I appreciate that!
Great video Chris! Too bad you're living on the other side of the big water. Keep on doing these videos!
Sweeeet! You are a good logical tech ! Saved another classic :- ) Woohoooo!
Thank you for your kind words and for watching.
Nice Fix Sir….!!!
Thank You
Your vids are excellent
I appreciate that! Thanks for watching.
nice save
Well done 👍🏼👍🏼
Thank you! Cheers!
The terminal tag strips are available all over the place, Antique Electronic Supply, TubeDepot, valvesNmore, but I just usually throw multiples of each size into my cart when I make an order from one of the ubiquitous Chinese parts suppliers.
Dan
Dan, thanks for the info.
Thanks I enjoyed that...
Thank you so much for watching.
AWESOME!
Thank You!
Digikey has those traditional style terminal strips.
Thanks for the info.
You beat me to it by 2 hours...
That Problem with the power and transformer. I have a similar problem on a Pioneer SX-939 I am restoring right now. I get a bright dim bulb when turned on but if I unhook the two red wires from the power transformer to the power board light goes out. Obvious I had a short some where on the power board. Going to be a run down to find it.
You'll find the issue. Using that dim bulb tester you have no worries about damaging your SX-939 while you troubleshoot the problem.
Thank you for Nice video! Mvh Henry Johansson Sweden 🇸🇪🇺🇲🇸🇪👍
Greetings from the USA. Your very welcome and thank you for watching.
@@vintageaudioaddict Thank you Sir! I Have A pioneer sx1250 i Wonder what components i must exchange ? Is there any kits that's on the market with spare parts so I may exchange the ones in need. U might recommend? Regards! Henry Johansson Göteborg Sweden 👍🇸🇪🇺🇲🇸🇪
Hi Chris, thank you for these excellent videos, I can only imagine the amount of work it takes. I was wondering if I can ask your opinion on the risk of buying expensive vintage equipment. When does a piece of equipment become too high of a risk, or is there always a way to repair something? For example I recently bought a mint condition fully functional Mark Levinson No.32 preamp for $10000, my dream preamp. It is however pushing 20 odd years, am I playing with fire? Are there components in these equipment that can't ever be fixed should they fail. I contacted Mark Levinson and they discontinued support for parts for this product in 2008.
First of all I'd love any piece of Mark Levinson. It's just never happened. Congrats on yours. For me, vintage audio is just something I really like. I'm not concerned if the value goes up, down or even if it breaks. Old electronics do break and that's just part of it. If you got your dream preamp, enjoy it. Probably your No. 32 will still be operating fine for many more years. If someday your No 32 does break most likely it can be repaired. Enjoy!
Nice unit and great repair job. When I opened my Marantz 2220b I noticed that the plastic bulb holder was broken. Probably heat from the original incandescent lamps. I used cool blue LED lamps, so hopefully it wont get any worse. And I'm hoping the new vellum paper won't yellow again. I have been using Deoxit D5 on contacts and F5 on volume and balance controls. Does that sound right to you? Thanks!
Yup! Sound Good! Keep enjoying your 2220b. She's a very nice receiver.
Best Video ❤🎉❤
Years ago I serviced a rare 200watts Marshall amp guitar head.....itvwas a nightmare....intermittend power tranny short on the plate voltage winding....i needed to rewind that....guess what... No.. I had a talk with its owner and ordered a replacement...along with half of the components due to out of spec or already burned down....sometimes we have to go the full distance... 😉
God, I want that unit.
She's an impressive receiver.
Congratulations on the transformer! You wouldn't want to sell one of those units would you? 😊
Ya, no kidding. I've read so much about them failing that I was worried about it. I'm not looking to sell at the moment but I'm not getting any younger. The day is coming sooner then later.
Is the wooden case for the 2500 number wc-24 ? Thank you.
Great work as usual I'm wondering would you sell it since you now have 2 🤔
Thank you. At some point I will need to sell some of my equipment including these 2500's. I guess I'm just not there yet.
@@vintageaudioaddict ok if you can remember me Thanks 👍
Awesome video! Maybe you would enjoy a 3D printer to make your own parts? Their cheap and you could sell them too.
Thank you. Not a bad idea I just need more time, lol.
Subscribed from Australia. I had one of these but like all 70's electronics they sounded terrible compared to modern technology. That amp stage has a damping factor of 60. Modern quality analogue stereo amps are more like 800 damping factor. I bought the 2500 here at a deceased estate for AU$200.00 in 2005 and sold it in 2010 for AU$6,000.00 It was working perfectly but just sounded awful. The fact these needed a fan says it all. My daily driver is a 2018 Rotel RB 1582MKII rated at 200W/channel into 8 ohms. I bought it new and it sounds absolutely gorgeous! Cheers.@@vintageaudioaddict
I appreciate this video so much. I never have good luck, but I still keep trying. My question is, in the beginning when you replaced the soft start resistor I think that is what you called it…there were two resistors, and it looked like you replaced it with three. Can you tell us why?
Thanks for watching! Yes, there are now three resistors instead of two. One was to replace the open resistor. The other two resistors were installed in parallel to control the fan speed. Those two replaced the original resistor. This was a mod to slow up the built in fan a little for less noise but still provide plenty of air movement.
@@vintageaudioaddict thank you so much for taking the time to answer me. Now I need to demonstrate the patience and problem-solving skills that you have and I’ll be able to get myself out of the jams that I get myself into. I seem to have just enough confidence, and lack of ability to get myself into trouble. Thanks again.
Really like your videos. I was wondering if you would be willing to repair a vintage HiFi receiver for me, paid engagement?
Nice move from the prev tech... Replacing a zD with a different type...what did he think...? Ooh need 14volts having only 7 volts types... Ooh..nevermind it will work anyway..?🤔🙄 😜
👍🏻😎
Thanks for watching.
@@vintageaudioaddict 🍻
Schiit that was loud at the start.
Thanks for watching!
Did you over pay? Don't know, you didn't state here what you paid for the unit.
I thought vintage Marantz receivers were worth so much because they were built so well. Skylabs Audio keeps saying Marantz receivers are expensive because they were built like a tank (Maybe like a Russian tank). Better off with a Sony or JVC from the 1990's for your music listing needs. Much cheaper and with less problems.
Great ❤ love it 👍🏻 go on 😎 cool Content
Thank you so much!
