I've tried to search for Enzo's Peavey parts cross reference topic without success. Need the cross ref for CR12 13886 - I broke it while servicing the driver board since it's clamped to the heat sink.

I believe Steve stickied it in the schematic request section.
It is a selected for voltage drop dual diode. Easiest thing to do is call the parts dept at PV and order the exact part from them.Education is what you're left with after you have forgotten what you have learned. -

So visual inspection of Channel A PA board: R117 charred the board but is still functional and C104 is fried (probably a short but it just fell apart when probed). All output devices pass the DVM test and CR101/2 test good. Original complaint was that channel A didn't work - no blown fuses. These components are part of the output zobel?? I'm assuming that C104 failed and was the root cause of the problem. Anyone else care to comment before I put the PA board back together?Comment
