I recently had to change out my rectifier because it was bad and blowing fuses. The recommendation was to change it out so I did and everything is fine sound-wise and functionally. However, I have noticed that when the amp is on (not in standby mode), I hear intermittent crackling and little pops when I'm not playing. Has anyone else experienced this or know what the problem (if any) could be? Like I said, the amp sounds great and is not limiting me any play time at all. I'm am concerned about the noises though. I would like to fix it now before anything major happens should it get worse.
Any suggestions/thoughts will be greatly appreciated.
thanks, Bill (bilbal)

Mine did that when I first got it.... I swapped out the middle preamp tube (12at7 for the reverb) for a new one and problem was solved. Of course it could be any of the other preamp tubes too?? Maybe tap them and see if one is noiser than the others through the amp?

General Maintenance: • If you experience intermittent crackle/static type sounds make sure the 4 screws that secure the chassis are tight. If a bit loose, the chassis will lose connection to the RF shield.
This is from the manual. My problem has been solved. Thanks so much for your help. I appreciate your time and patience.
Karma for you my friend.

Well I thought it was fixed but here we go again. It sounds like there is interference in the line or something. It's not loud enough to ruin my speakers I don't think but it's a PITA to hear it. I guess I have to start playing the find the f'ed up tube game. Where and how do I start? Please guys any help? thanks. Bill

Start with a good tube, one you know is reliable. Go thru your preamp tubes. After that I'd order a new Quad of JJ EL-84's from Doug's Tubes if you don't have an old quad sitting around to try. I'm also assuming that you've swapped guitar and speaker cables to take them out of the equation of possable offender's. Is it doing this with ALL of your guitars? Could it be a bad connection at the jack of the guitar or amp?

Thanks Jason - sounds like a good way to single out the bugger that throwing things off. I'll give it a try. I have noticed that it tends to go away after the amp is nice and warm (??)
Hey BTW, I don't remember you telling me you had a 65 amps? Did you buy since the 66 or have you had it for some time? How do ya like it? I have been hearing great things about them.
What else is cooking?

Always worth while to have a whole spare set, including rectifier. And fuses...
