In Reply to: Depending on how loud the hum is,there are a couple questions. posted by Michael Samra on August 5, 2013 at 08:55:59:
Michael, I've put all new tubes and all new filter caps (electrolytics for now, but they're all new.)
This gives me a few ideas. I'll A/B the tubes and check the sockets and also all the ground solders.
A clue here: the hum gets loud on startup and then goes quiet. You can still hear it though. Level control doesn't affect it. Almost sounds like a capacitor.
Thanks.
