Marantz Model 22 receiver, parts list or rebuild/recap list help needed

[Gc_17311]

Hello everyone. I just picked up a Marantz Model 22 receiver that I’m going to refurbish. I looked online for any rebuild kits available and there’s only one available on eBay from the seller that I will never work with again. My question is does anybody know where there’s a build list for the Marantz model 22 of parts to replace. Or if anybody has done a Marantz model 22 who could offer me some guidance. If I have to, I’ll have to go through board by board and pick out piece by piece but I’m trying to save a little time. Thank you once again everybody for all your help. this community is invaluable and amazing. G

Hello,

I just did the amplifier and the power supply filter caps and power supply board P800. I also changed out the safety cap with a new one. A y safety cap I believe.
I don't listen to Fm and it is in the garage so I'm not listening to the turntable. thusly I didn't order any caps for those boards. Perhaps I'll work on it again at a later time this summer and replace more of the caps. I guess that would be the wisest thing to do.

I just went through the boards and measured the width of the caps and lead spacing and voltage requirement--was only about 15 caps or less. Got them within a week at digikey.
Some pre set kits you order can have some wrong caps due to a revision and you'll spend way more than you would if you did the list yourself. My .02

I put a red dot on all of the new caps so I know which one I did. I also did one section at at time so that a problem could be narrowed down to the section just completed. note the polarity before removing anything because the silk screening can be wrong from time to time. One of the 4 resistors towards the back of the amp board was way off so I replace that too. I got my service manual from hifi engine. They have parts lists and the schematics for Model 22 and Model 22R. I have the first one.

Take lots of before pictures from different angles (o you can see where that black wire went that is hanging off after removing the 1000uf caps on the p800.) They are can caps with 3 neg pins and one positive pin. When you're messing around on that p800 board, don't lose the mica insulator underneath H801, if you re-install without it you'll have issues with R801 getting nice and hot, don't ask me how I know.

Good luck,

Daniel
