Tube Amp Hum, No Sound

[lestakanez7814]

I have a Crate Palamino Class A 15watt Tube Guitar Amplifier that i literally JUST got repaired because it was making a very scratchy loud noise when i turned it up too much. That problem is now fixed, however, when I got home, I plugged it in and turned it on, and it is humming really loudly, but my guitar doesn't make any sound through it. It makes the same sound without my guitar plugged in, and I have tried several different guitars, and chords. Any advice? Help would be appreciated!!!

Then I would take it back to the shop that repaired it and point out politely that it is not working right after their repair.

it could easily be something to do with the input jack or panel controls damaged during reassembly.
