SOLD!
While I was building my 300B amps a few years ago, someone suggested to me that I pick up a PSVANE 300B tube to use for testing purposes as I built my amps and was tweaking the power supply so I wouldn't inadvertently damage the more expensive EML meshplates that I picked up from Jac. This turned out to be a useful suggestion, but now that my amps have been completed, I have a single tube laying around that probably has no more than five total hours on it. It ran with a B+ voltage of no more than 400v and its heater never saw voltage above 5.15v DC. It's virtually brand new and works/sounds great. I just don't have a use for it anymore.
Perhaps someone else might find a use for it rather than having it collect dust in my basement.
Price: $$$ delivered to your door in the continental US.
This is the circuit that it ran in:
