Hey everyone, Pyro here. New Here and Im a newbie to good stereo equipment, but i have everything working except for this damn hum.
So for my sound system, I have a sundown car woofer hooked up to a 1200w car speaker amp, powered by 850w computer psu. It has a ground loop isolator on it. It needs it, or it alone has a huge buzzing noise coming off. (That got rid of that hum)
My problem is, i am now listening to records. My record player is a crosley, it has a pre amp built in(no ground nut), but i have a tube phono amp that i have the turn table use phono mode with. when i plug this phono amp in, i get a slight humming again. once the amp is unplugged it goes away.
If i unplug my 3 pronged outlet sub setup everything is fine. If i remove the phono amp and use the built in amp on the crosley every thing is fine.
I would like to keep both amps. What can I do?
