I have finally got the speakers, amp, pre amp, up and running.
But now….I keep having this humming 60 hz sound from the speakers. I have a sys volume control and the hum gets louder the higher the volume goes.
I also have a pre amp mani. I have tried messing with the gain and it helps a little but its still there.
I have a ground running from the turn table to the mani and I have tried messing with that and still nothing.
I’m at a loss.
I built the ESO 7 baffle speakers and the ice amplifier. Any solutions would be greatly appreciated.
Update: I moved the equipment around and now it’s worse with 120hz…
