I have a NAD 320 integrated Amp in need of repair. Does anyone have service
manuals for this?
The PSU seems OK - +/- 44V DC.
If I feed signal into an input I get a much attenuated version out from
the Pre-Out terminals. Volume control varies the level and source
switching seems to work. I think the Pre-Out level should be much higher.
If I input a signal into the Main-In terminals I get no output on the
speaker terminals.
Any suggestions or data welcome.

Thanks

Graham


I would first test the AF power output transistors -- unless you are dealing
with an integrated module (can't remember what NAD used in your model)
