NAD 2150/3150 Schematic + advice

[steve_aus]

I am trying to fix an old NAD 7150 Receiver / Amp which has DC on the output, preventing the relay from closing.

I think I may need to change some caps.

I have a 2150 schematic (has same main amp) but it is a bit hard to read.

1. Would anyone have a schematic for NAD 2150/3150 ...7150 and/or any other service information that might point me in the right direction

2. If anyone has particular experience with these amps and can suggest likely culprit, please feel free.

Thanks in advance

Steve
