I may try that. The 6SN7 heaters are run from a separate filament winding than the 6L6s. The China tubes really buzzed, but I subbed a couple I had on hand and it quieted a lot. Still trying to track the hum down. I may even have to set up the heaters on these as filtered DC. I have a dc power supply I may try to see if it helps. It really isn't bad, but with the filtering on this amp, I feel it shouldn't have any hum at all. Going to do some more checking.
If I could find the place called "Somewhere", I could find "Anything"
