Octave Research OR-1 schematics/service manual/

Can anyone help. I am looking for schematics/service manual/diagram of this old power amp.

The amp was designed by Andy Rappaport. You might try googleing him. I found him a few years back - he was working in some other high-tech industry - he was more than pleasant to deal with. Good luck with the hunt.
If you need info on this amp contact me. I have three of these and three Rappaport Amp 1's.
