While playing at my church I started to get a nasty hum/buzz about halfway through the service. This hum got louder as I turned up and would go away when I turned all the way down at the amp. The hum was still there when I unplugged my guitar. I also tried different tubes both preamp and power.
I rechecked my solder joints and redid a few that looked suspect, and I twisted my white & yellow OT wires tighter together, I'd already twisted the 2 orange wires per Ken's instructions, but then I also twisted the 2 red wires from the PT to the diodes (which I soldered to the underside of my turret board). I also sanded the connections in my fuse holder.
I put everything back together and this time I still had a buzz (maybe a little quieter?) but no sound at all from my guitar. Tubes also seemed redder hotter than usual. My first thought was that maybe I'd connected the wrong blue and brown wires to my power switch. So I powered off and after waiting a minute removed the blue wire - and when I couldn't get the brown wire off with my hand I used my rubber grip pliers - I must have touched the chassis as I pulled the brown wire cause I got a big pop/shock - didn't hurt but sure scared me! Now there's a small black burn mark on the brown wire, but it doesn't really look damaged other than that. Upon closer inspection I had the correct blue and brown wires on there.
Now I have no power, no sound at all.
I tried replacing the fuse with one had laying around (250v 3amp slow blow) is that ok? Still have nothing. I'm afraid my technical (in)experience is really limited to the simple replacing of parts my electronics classes were over 20 years ago - so I'm completely over my head when it comes to trouble shooting.
Hoping some of you guru's can help me out - I need to play again this weekend and really don't want to go back to using my POD. Any suggestions would be much appreciated. I'm off to work now, but will check back in later this evening.
FOR YOUR SUGGESTIONS AND HELP!
