It's a JJ 6V6 S...
It could have been crud in the tube socket. Swap 'em back and see. It could also be a loose connector in the tube socket that needs to be retensioned.That what it was!
I swapped it with the 6v6 from my other amp, and now they both work. ???
Cool, thanks for your help with this. I'll switch them back tonight to see if it works.It could have been crud in the tube socket. Swap 'em back and see. It could also be a loose connector in the tube socket that needs to be retensioned.
That tube might be on its way out too - I'd recommend replacing it if it's all suspect.
In looking up info on your amp, I see it's single ended cathode biased and can run multiple tube types. I'm just guessing, but I suspect it runs a 6v6 on the hot, to very hot end of the spectrum. I would say that the 6v6 you took out of the amp is probably at the end of its useful life. Sometimes a tube can go (redplate) and still work after it cools down. However, IMO, once a tube redplates, it's cooked and should be replaced. It's not worth the risk of it taking other components with it when it does finally go poof.Cool, thanks for your help with this. I'll switch them back tonight to see if it works.
