It started yesterday when I started getting this very loud siren-like sound after I turned it on and started playing (I let it warm up a good 4 or 5 minutes.)

I thought that some of the tubes might be loose so I checked them out and made sure they were well-secured. Fast-foward to about 5 minutes ago and it happens again! I have a feeling something is wrong....

The amp is a B-52 AT212 combo amp (reverb tank is broken so might that be the problem?)

Ugh...I just got this amp about a month ago and I would hate for it to crap out already. I have no idea what could be going on but I hope it's something easily replacable like the power tubes or the fuse....

Its just a noisy amp, i have the same amp. Just get a noise gate, it clears it up real quick.

The thing is, this very loud siren noise happens on EVERY channel, including the clean channel.

This isn't background noise, this isn't feedback...this is a "I don't think it's supposed to do that" kind of noise.

Also, when it happened again today, I played at a very very low volume (less than 1) and a very loud siren noise still came out. I KNOW something isn't right here.
