Reply to "Proto Sound 2 5v board repairs"

They are the PV diodes and rated at 1 amp and probably susceptible to age failure.  Make the DC for the various  other Power Supplies on the board.

Way back I saved a few with getting out the one bad diode, but a real pain and not always successful.  I also (once) separate boards and then reattached via jumper wires just to test, and it was not successful.

Under the rectifier you will find a rev code for the boards, you might want to work on the K, they were the last and best board.  G
