Soundcraftsmen PCR800 and PM840

First post! I've been a lurker for a while and finally registered a week or so ago. I sure wish this site had been available to me when I had more time to work on projects!

Now to the point; I have one of each of these amps. The PM840 is in use and runs fine, but the PCR800 does not.

Does anyone have schematics for either of these? I think they are close enough in design that a schematic for either would work for both.

I would also be interested in knowing what people are using for substitution semi's in these little monsters!

I have searched the archives, but havent found much. I just hope that a couple of people here are still playing with these :)
