I was experiencing some crackling and fuzzing noises in my 67 deluxe reverb, and trying to track it down. So today I swapped the rectifier tube which seemed at first to fix the problem. Sounded better on the first power up. However, the next time I fired it up, I got a strange buzzing sound when I turned on the power switch but before I turned the standby switch on. I was a little bewildered and I *think* I turned the standby on which blew the fuse.
Does that sound like a bad rectifier tube? I've never heard an amp buzz with the standby off before...Anyone have experience they'd like to share?

Btw, the filter caps have been changed.
