Hmm, no phono in... just a pair of RCA's. It's a Yamaha M-40 power amp.
The plug isn't polarized.
In the manual, it says to connect the ground to the pre-amp ground if there is a buzz. Unfortunately my pre-amp has no ground.
You were right about switching the ICs. Last night I started to think... 'wait, this doesn't make sense that it would only be coming though one channel.' I swapped the ICs with another pair, and the issue was solved.
I have no idea how this could happen - maybe something is wrong with the shielding on one of my ICs? They are brand new, so I didn't suspect that at all.
Incidentally, I had to turn my amp on and off many times while switching power configurations around. Also, some music was distorted in that right channel (crackly, fuzzy) at times... could any of this have damaged my amp / speakers?
