I would be very grateful if anyone could post schematic or even better, a service manual for Proton 930 receiver.

Try this one. Should be the NAD equivalent.

Hi Ylli,
I know about this reference to the NAD,but unfortunately there's no resemblance. The Proton has a differential input (dual npn transistor),no emitter resistors etc.,but thanks in any case.
