NAD 7130

RM · 25th August 2011, 09:39 AM

Can anybody help me with a schematic on this one? I am missing the positive halfcycle in the preamp, power amp is ok though. These old NAD boxes are so littered with flying leads, I am reluctant to start without a schematic.

Regards

NAD 7130 SM Service Manual free download, schematics, eeprom, repair info for electronics

I would trace the input signal along the input circuitry and find out where it goes wrong.

Just Googled NAD 7130 and found free download of Manual. Anyone have knowledge of the breakers in each main amp section?

It's a breaker.

If you have a problem with it, jumper across it and use an external fuseholder.
