Fender Twin Reverb Amp Troubleshooting

[Chris Simpson]

My 1970's silverface Fender Twin Reverb amp powers up but I barely get any sound out of it. If I turn the volume all the way up I barely get any sound out of the normal channel and I get no sound out of the vibrato channel. I was playing on it, I heard some static and a crackle and then nothing. I checked my cables and they are fine. I had an extra set of tubes so I swapped them out and nothing changed. I swapped the #1 and #4 pre amp tubes with each other and the #3 and #6 with each other and nothing changed. I don't believe there is any issue with the tubes, but I don't know where to look next? Any troubleshooting ideas would be appreciated.

Hope you got it taken care of.

If not, I would refrain from turning the volume up all the way until you have it looked at.
