Hi everyone,
I've recently purchased a used Mesa F-50 combo which sounds fantastic. I wasn't sure how old the Mesa brand power tubes were (and was tone curious), so I tried a pair of JJ 6L6 and a pair of Svetlana 6L6's that I had. Only slight tone differences really, but I encountered a problem new to me.
One of the power tube sockets seems to have an issue, The filament in the tube in that socket won't heat up occasionally. I have to pull it, re-insert it, and sometimes even swap the tubes around to get them both to light up.
I have tried it enough to learn it is not a particular tube, just that particular socket.
Any ideas? I have cleaned the sockets with contact cleaner.
Thanks in advance!
