What's with the Variac? In my experience, all Variacs buzz, but some buzz more than others.
How to see if there's DC at my AC outlets?
Can I simply take a voltmeter, set it to DC, to see if there's DC on my AC lines?
I have Joule Electra monoblocks with an external variac, and it has a tendency to hum / buzz rather loudly at times. I am wondering if its related to DC being present at the outlet. It's not due to ground loops, that I can tell.
Thanks!
