I'm getting a popping sound in the left channel of my NAD 216 thx amplifier.
I've isolated everything:
Switched speaker cables, no effect
Switched input R/L: no effect
Hooked up rig to a Harman Kardan receiver, and no popping, so it's not the speaker.
The only thing I haven't done is the deoxit thing, which is what I'll do tonight.
So...any ideas?
