Does anyone know where I can obtain a schematic or service information on the above unit please.
Been given a non-working unit and have no clues as to where to start regarding voltages (or anything else for that matter)!
Thanks.

Rauch Precision (British high end audio from the70~ 80's)

One of the early adopters of Hitachi's mosfet in their audio Amps .
They had several simple, solid "Tube sounding"Amps.
Stability and TO3 package cost is what killed the mosfets as they never took off in the market.
Hard to find & expensive if you have shorted Mosfets.

Someone has a copy of power block 4 posted here:
