I bought a 5150 combo 1 month ago. I was told it was retubed 1 year ago and played twice. the tubes are JJ 6l6gc and 12ax7. I was playing a gig and it just cut out. There was a hiss out of the speakers, but no guitar. both channels did that. I took out the tubes and put them back in where I found them. I turned on the amp and it worked, but there is little gain and the post gain adds almost no volume. the same day I bought a hosa 2 button footswitch and a stereo cable. it will only switch if the amp is in the lead channel. I dont know if that has anything to do with it.

The amp has to be set for the lead channel for the footswitch to work. Try plugging a jumper cord in your effects loop and see if that helps. The loop jacks get dirty and can cause the amp to cut out. Sometimes just plugging a cord in and out of the loop jacks a few times will clean them up. Jerry

that had no effect on the sound, could it be blown power tubes?
