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"
