Question about Amp Buzz

I bought a 45410 off reverb about a month ago and it's an amazing sounding amp, but lately I've noticed a terrible buzz when i hit certain notes. I first thought it was the rectifier tube, so i changed it and no dice. Now I'm thinking its one of the speakers. Will a speaker make that type of buzz when it goes bad? I'm about to start pulling my hair out if I can't find the issue.

re: Question about Amp Buzz
Is there a ground switch? What kind of power are you plugged into? Power tubes can also be culprits

I suppose it could be a speaker issue, but in my experience it's usually ground, tubes, cables, or just "dirty" power

Yeah there is a ground switch, but it has a 3 prong power cord. It's plugged into a surge protector that goes into wall Jack. I can order some new power tubes. That's not a problem. I might take it to my tech and let him look at it. I know it needs a cap job. It makes some crazy scratchy sounds as well.

re: Question about Amp Buzz
have you made certain that it's not a cable, guitar, or pedal issue?

Have you checked all the input jacks?

I know it's not cable and guitar. Right now I have it jumped, but I'll try plugging straight into each Jack Tom.

re: Question about Amp Buzz
Is it an electrical buzz sound like when you have a scratchy pickup or jack, or is it a more vibrational buzz? If vibrational, something could be loose in the amp/cab and certain notes will set it off. Depending on how my drummer is tuned, when I hit certain notes on the bass, it causes his drums to vibrate/buzz like crazy.

re: Question about Amp Buzz
The buzz is a vibrational type of sound. Whenever I hit a certain note it makes a bad buzzing noise. I've taken it in different rooms and plugged straight into a wall outlet and the buzz me is still there. I'm gonna run it to my tech and let have a go at it.

Something is loose in the amp/cab. Hopefully it won't be too big a deal.
