Yeah, for me I tried to use 6SN7 tubes and ended up with PSVane since it had less buzz.

Nice! For me it was the Sylvania that has absolutely no humming. But I had great luck with Tung-Sol and EH too (after an actual burn in period of 24-48 hours on the EH).

But some tubes crackle when I move my potentiometer, which I find super weird. The Sylvania is the only one not doing that.

Yeah it seems to come down to chance sadly. My Sylvania had a buzz that didn't go away after burn in, but the new PSVane's were perfectly fine. I tried some WE403a and the GE replacement and the GE were good but WE weren't.
