I did a similar thing with an old netbook and a Schiit Modi. I installed XBMC on it (Linux version), and set up my main PC as a media server. I control it with Bubble UPnP on my Android phone. Who needs a Sonos system? wink.gif

Well since it has been a little slow, I thought I would give an update on the Mac progress. I was going to initially drop my 2205 off in Knoxville to be restored by Terry Dewick. For 200.00 he was going to do everything except the main filter caps(an extra 200.00 for those). It was going to be a three month turn around, but I thought that sacrifice would have been more than worth it.

So I'm the meantime I thought I would get it up to snuff cosmetically. I ordered a new glass, cleaned the pots and switches, adjusted the bias, and gave her a good cleaning. I also decided to make my own led lamps. Audio classics sell led conversion kits for 150.00, but for 7.00 in parts I had enough to make my own for both the 2205 and my c39 preamp. The bi-pins as always were easy. The bayonets were a little tricky, but still fairly easy.


Then I thought, if I can do something as complicated as desoldering lamps from a pcb board, making my own, and soldering the new ones to a pcb board certainly I can do something as easy as caps, diodes and resistors. So I decided to do a full restore myself....replacing all electrolytics, bad diodes, resistors, and transistors. Well after 97.00 in parts I was able to pull it off. About 1/3 off all the caps I pulled were bad a few more out of spec and a few bad transistors and diodes. I also had to replace a few ic chips as well. Here's pics of the finished boards. I used all nichicon muse premium caps except for a couple of panasonic fm on the meter boards which aren't I the signal path, and the two large axial caps on the power supply board which are vishays.








I fished everything up with a good defluxing with acetone. As you can see in the following pics, acetone does a very good job as a "defluxer" biggrin.gif

Oh I also replaced the main filter caps. Those things are huge!! There a little over 4 inches tall and just over 3 inches in diameter. I did a small mod to them by adding a couple of 2.2uf/250v panasonic polyester bypass caps as seen at the top of the first pic.

I'll post pics of the what it looks like with the new face and leds tomorrow. Before the restore, it sounded darn good. It beat everything I've owned except for the fisher. Now I would say its the solid state equal of the fisher, with it doing a couple of things better. But the fisher also does a couple of things better as well. More impressions to come. But I'm very pleased with the overall result.

Thanks SO. Years ago the thought of recapping terrified me. But my skills and knowledge has gradually improved over the years and it just dawned on me of how capable I am at this point.

Stereo surgical procedures still have me feeling a bit cold, and it should if I'm to remain unprepared. I hope to learn more; accomplish more in the coming few years. The excitement in this hobby will eventually push me in the direction I need to go.

smily_headphones1.gif same here. I wanna take some electronics courses at the CC and recap my Marantz 4400. Its got some nasty crackle in the left channel (kind of like hearing the ocean in a shell) that no one but me seems to notice. Not even the guy at audio specialties in Portland could hear/find evidence of it. Hopefully if I recap it and replace the main filter caps, that'll fix it.

Excellent work there, Moody!!! smily_headphones1.gif

Picked up a nice Marantz 2226B for $125 from craigslist. Its pretty nice sounding. Almost mint. Scratchy volume control but will spray some contact cleaner in it tonight. A couple dead lights but will buy some blue LEDs next month.

I've been to every pawn shop I could find today and only saw a crappy AKAI R2R so I'm glad I could get this.

Oh and an almost mint PF Obscured by Clouds LP today.

Very nice! Did you choose polyester bypass caps because polypro, teflon or others would not have fit?

Great score! That's is said to be one of the better sounding marantz; even suprassing some of the totl models.

Thanks. I chose the polyester because those are the type of caps EW likes to use for his bypass caps. I don't know why, but can't argue with the oracle.:D

As promised, here are some pics of the finished set. Sorry about the crappy quality, these were taken with my iPhone. It's never able to capture what the leds really look like.
