I bet your issue is with the power supply being too close. I had the same issue and when I moved the power supply further away the noise went away. I love the amp but hated the hum. Fixed now though. Good luck!
Hum...ZYX with Tom Evans Groove Need suggestions
Hi all, I need help with with hum I'm getting from my ZYX Airy 3 and Tom Evans Groove combo. Never had hum issues before with a number of other phono's I've had. The hum is louder on the left side than right, and if the Groove didn't sound so good I would've gotten rid of it. Thanks in advanced.
