OK, I successfully got this unit to make music and not smoke thanks to the great help here. For info - http://audiokarma.org/forums/index....rd-mislabeled-need-help.813236/#post-11400319 I have moved on to the power supply and figured a new short thread was appropriate for a couple of questions. I recapped the board and set the DC voltage per the manual last night. After each bit of work, I plug into my dimbulb tester as I learned from you guys. In addition, board contains 4 diodes: 2 - S1B-01-02 - searching told me to buy UF4005. This seems correct. 1 - BZ-140 - I think this becomes a 1N4744A, so I purchased, but now i'm having trouble verifying this is correct, can anyone confirm? 1 of WZ-071 - I bought a 1N5236B, and also can't seem to confirm this choice either. Maybe i'm crazy, but thougt I worked all this out from searching the site. I clearly need more schooling..... Thanks for the help.
