Info, schematics for Wright sound AU70 amps

I just bought a pair of Wright Sound Au-70 amps. I have a bit of info on them but nothing that would help to repair them if necessary. Can anyone point me in the right direction?

what is needed to be repaired? tube amps are simple and you don't need any schematics.

These amps have internal bias meters which don't appear to be reading properly.

remove meeters and use external at the bias terminals.
