Replaced power tubes, but one isn't working although it's good?!?
I've just replaced the old 6L6 GT power tubes for JJ's 6L6 GC. One tube didn't light up so I've switched position and the tube light up, but the other tube don't. I am guessing it's something to do with the socket, but I've tried the old tubes and all still work...
I appreciate your help on this, because it's a bit mind bending.
Thanks a lot,
