Thank you Craig for providing copies of those schematics! I replaced some op-amps and a transistor and the unit seems to be working fine now.

Hello Craig,
I hope this message reaches you. I am trying to help a friend with his broken Crate PCM8+ Mixer Amp. The unit immediately blows fuses when powered up. I thought that there might be a damaged amplifier which is drawing too much current. There is a wire harness connector that could easily be incorrectly reversed. I don't believe I can do much without a schematic. If you can share your schematic with me, I may be able to help. I saw the Spanish website which claims to have the schematic. I am not comfortable purchasing from sites I am not familiar with not to mention that my Spanish is limited. Thank you for any help you can provide. My email address is:

Hello, I know this thread is a bit old, but I have been everywhere looking for a Crate PCM-8 Schematic. I believe the transformer in my unit is blown and the schematic would be a great help getting it back working. My email is muushusp@gmail.com and it would be great if you could sent a copy my way. Thanks,
