Musician Gear & Tech Discussion

I did a little research. Take the old cord out, disconnect the polarity switch and remove the .047uf capacitor connected to it. The hot lead of the new cord should be connected to the fuse, that would be the brown wire on the replacement cord I sent a link of (or the black if you find a US version in a hardware store....home Depot should have them). The neutral gets connected to the power transformer input lead (the side of the aux receptacle that the fuse IS NOT connected to). The neutral will be the blue wire on the cord in my link or the white if you pick up a US one at Home Depot. The green ground wire gets connected to a ground point in the chassis....like the transformer mounting screw I mentioned earlier.

Thanks ye very muchley HDriffraff!!! That's what I wanted to know!!
Wasn't sure what to do with that .047uf capacitor and if the switch should be wired to anything if I used the 3 prong cord. Maybe I'll wire in a little battery powered alarm to the unused polarity toggle switch,
Label it Super Turbo Boost as a joke to scare people that mess with my amp settings.


Cheers and thanks again!

Well...I was trying to hold off doing the fix until after we did this recording for this interview....well, that was a BAD idea. I had a direct out on the amp to board and had my guitar in my hand and touched the standby switch and got shocked to hell, I couldn't let go of my bass and when I finally let go of the switch my bass went flying out of the hand! Lucky it's a Peavey!!! My drummer thought I bought the farm.
Ok ok...I guess I better fix it now, probably don't need to follow Les up to heaven!!!

Hopefully the new cord fixes the problem.

Well, it seemed to fix it, I do have a little bit more noise than before, I adjusted the hum balance the best I could. But at least there are no shocks anymore.

I seem to remeber someone advising you against playing anything that shocks you.
Glad you were not killed n the process.

Nice job! Glad to hear it worked out for you. The hum is likely just line noise on the circuit you are plugged into. You could try plugging into another circuit. Sometimes other items connected to the same circuit cause that noise like appliances & flourescent lights. It could also be a little ground loop hum if you have other devices with their own AC power source plugged into the same amp. I would take a little bit of hum over getting zapped while I'm playing anyday.

I tested the body for voltage with a meter when I turned it on...just in case
I have a much nicer longer heavy duty cord on it now and feel better using this setup and not worrying about grounding problems and the nonworking polarity switch.

I played with getting it on it's own line and adjusting the Hum Balance more and it seemed to clear it up. When that Amp is on full volume, you can be standing right next to it and not even know it's on.....but don't hit a note or you'll knock yourself over.

It's my favorite Amp ever. I haven't seen many Ampeg like it with all metal knobs. It's a big heavy duty metal menace, all the lettering on it has long disappeared but it's so clean and those 100 Tube Watts destroy much larger solid state wattage.....and the warmth and overtones, the growl it gets turned up...I run it straight most of the time and only a Fuzz Box for 2 songs.
