So I bought this amplifier in march of this year, and I went in to practice my guitar, when all of a sudden, it started humming very loud, and there is no guitar coming through. I immediately grabbed another cable and still it continued to hum. I then moved the amp into another room to see if it was a ground issue, but it was still humming. I checked the tubes, pulled them out and made sure there was no dirt and that they were fastened to the amp correctly. I do not know how to tell if a tube is bad, but they do light up. Even without any cable or guitar plugged in, it still hums. I'm just looking for any tips or guidance on what I should try next. I love this amp to death, but she's shits out loud right now.

Eternally in debt if you can help me fix her.

I bought one of these a few months ago, thankfully I've had no problems whatsoever with mine. The only useful advice I can offer is, you might want to post this in the amp forum. Welcome to the forums to banjoe89
