Mark 2 Series schematics

Post by mwrath7 » Tue Jun 07, 2022 9:46 am

Hi. I'm new to the forums and trying to locate schematics for the Peavey Mark 2 Series mixers. I'm restoring a 1978 MC24. It has a problem with the +15V supply. Something is dragging down the voltage downstream from the LM325N regulator. If I remove the jumper connected to pin 14 I get +15V, but it's only reading around 1.6V with the rest of the circuit connected. I suspect a diode issue.

If the schematics for this unit (or even just the power supply board) are available, a link would be greatly appreciated.

Thanks!

A diode? I would check if any op amps or other semis are getting hot.

Did you put in a request for your schematics to [email protected]?
