Bad Tubes



“Hi Richard, it’s your friendly neighborhood amp tech.”

“Oh, hi! You have some news about my Tweed Deluxe amp?”

“I do, but you are not going to like it.”


“Okay. What’s wrong?”

“Bad tubes.”

So, after three sets of tubes, I finally have a working amp again. Not sure why the previous two sets of tubes didn’t work. They tested okay outside the amp but did not perform inside the amp.

I called up the tube store to ask for a return authorization on the last set of tubes. I had opted for the vintage package which consisted of two Genalex Gold Lion 6V6 power tubes, two JAN-GE 12AX7 preamp tubes and a JJ 5Y3S rectifier. It was an expensive order and I would like to have a working set on hand.

I would rather chew glass than play an electric guitar through a solid state amp. That said, tube amps can be very temperamental. And somewhat costly when faced with multiple bad sets of tubes.
