I’m looking for a schematic for the KAV-250 and have come up empty handed. I did see a post from 2007 with a hand drawn schematic of the output board. That helps. But really need the driver board schematic. I have one channel that starts making static/popcorn sounds the second I power up the amp. I can see the noise on my scope right at the input of the amp as well as the output. Very hard to isolate. Any suggestions would be great.

I have kav-150 circuit and PCB making drawings.
But I don't understand what you're asking.

I’d like to find a schematic and if anyone has info on know issues with these amps that could give me a vector Victor. I think it’s one of the to-92 transistors but freeze spray didn’t help me narrow it down plus there is prob 40 of those buggers on the board. Could be a resistor but there are over 100 on this board.
