Amp is a NAD3020i, an upgrade to my entry level cambridge however definitely now a vintage model.
This noise occurs only occasionally in the left channel. Seems mainly vocals and higher frequencies are broken up with distortion before returning to normal. Interestingly, I've connected the amp's "rec out" to a Line In on my sound card and recordings made on my computer pick up no disturbance from the amp's output at all. The distortion occurs through speakers and the headphone jack.
I'm no expert so I did have a technician look at it with a solder iron when I bought it. He said he could detect no problems but did suggest rotating the pots occasionally which can get dirty.
Take a look at the video and let me hear thoughts on this. Could the problem simply be dirty pots? I hope so since I really love this amp. My first quality entry level...thanks guys
