Peavey 5150 Combo 212 Amp Static Problem

Hi everyone,

Just a quick post here to see if anyone might recognize this issue with tube amps.

I just recently acquired a used Peavey 212 Combo Signature amplifier. Overall it sounds great once it kicks in after about 20 minutes due to this static noise I’m getting. Attached is a video I just created so you can hear the noise. I’m not sure if this is due to bad tubes, caps, or perhaps a pot somewhere. My guess is either caps or the tubes. I am new to tube amps specifically so I’m not in the know with all the noises these things make just yet. I came from using a Roland JC-120 which can be noisy as well. The problem here is this behavior is not hissing, rather an erratic sort of radio static.

Thanks for any insight into the matter.

Note, I do plan to change the tubes as I have no idea when they have been changed if at all. I picked up the amp at a used music store in Nagano Japan and was not able to test the amp, but it was practically given to me so I it was ok. Perhaps this is why!
