Hi
I have a Nad 3130 with very low volume. I have connected another good into the nad main section and it works fine. Connected the nad preamp into another good amp main section and it was very quiet which leads me to suspect the nad has a problem in the preamp. Any advice on what to look for. Could it be a capacitor or something else
thanks

If it's both channels, the problem is more likely to be in the power supply.
But, in older equipment, sometimes a dirty or worn switch can cause
problems like this.

Thats weird as I took the fuses out to check them..all ok. Put them back and now amp doesn't power on but fuses haven't blown. Switch ??
Maybe. Do you have a voltmeter? Check the voltages before and after the fuses.
Routinely I clean all switches, pots, and contacts in older equipment before checking further.

Getting 34v on two fuse outlets 29v on the other two. But power light is not on and no sound from amp
Maybe a voltage regulator after the fuses is bad. Can you carefully measure some circuit voltages?
Part of the power switch circuit is actually after the regulators. Measure the two regulator outputs first.
