I would bet that Marakanetz is correct. Probably Cracked solder joints. I got a 7120 receiver on ebay with a bad channel. I looked at several solder joints with a magnifying glass and noticed that they had a tiny crack in them. I also have an ADC equalizer that had the same problem. I fixed both with re-soldering. This is common with older electronics. Mine were in the joints for some of the selector switches.
'R' Channel Dropout on older Nad 3150 amp
Hello,
I have an older NAD 3150 amp for my second amp and it has started to frequently "drop" the right channel. It had happened once or so per month and could be fixed by turning the amp off then on. Or by balancing volume to right channel and playing with volume knob and turning way up and channel would pop back in. Now these same solutions work but require doing so multiple times per day. Any easy solutions to this? many thanks, e
