Valve queen still in business?

Take the amp head off the cab ? Worth a shot...

Nah, that doesn't work either. It's like a snare drum rattling when you hit certain notes. Sympathetic vibration. I wonder if they all did that or it's just these old leftover tubes being sold as NOS since that's all that's left.

Hmm. Must be yours because that's all I've run in my amps over the past few yrs, with the occasional quad of Mullard or Winged C that I'll throw in for a change of pace.
I have multiple quads and I've never heard anything resembling what you describe.

I have 6 sets here. All from different places. One set from Mesa, another from KCA, another from here and there. They all do it. Just the RFTs too. I've got JJs, and Ruby, and NOS Tesla, and EH, and so on. Only the RFTs do it. It's so weird.
