Question:
Ok, so I found some old posts about how people get shocked by amps with two prong cords. Was wondering if someone can tell me what I need to do to convert my two prong amp over to a three prong.
Answer:
Your amp should have always been grounded. Did you buy your amp new? If you somehow bought it without a grounding pin, then you should learn from that and remember to check the plug before buying a demo off the floor (something I had to check for when I bought my Blues Jr.).

As for a way to ground it, I'm not experienced in do-it-yourself electrical work, so I won't give you any explicit instructions, but I don't envision that it would be so difficult to jimmy up a fix yourself. However, I once again say that you shouldn't take my word for anything until you've been instructed by someone more educated in this field.
Answer:
Well, it wasn't a demo, nor a true guitar amp. It's a vintage PA amp from back in the day when they didn't use grouding plugs.
Answer:
i think you can buy a plug that you stick on the end of the 2 prong jack that converts it into a three prong i think
Answer:
Yea, but that won't keep me from getting shocked...
Answer:
good point, I read your post after i wrote it and yeah that was totally pointless sorry. I am out for summer and i turned my brain off.
Answer:
When I had my '69 Bandmaster Reverb retubed and recapped and brought to black face specs, I also had them change the power cord. I'd get an amp shop or some other electrical repair shop to do it.

I know exactly where your comming from. I still need to convert my kalamazoo over...
Here's a pretty good link of what to do (look at the 'safty first' articles)

I'm assuming that it is a tube amp; you'll probably want to drain the power caps. (200+V) If it is solid state, I'm not familiar with the power rectification. I would assume that a solid state would have a similar setup, although transistors won't need the high voltages you'd find in a tube amp.
Anyway, the process should be fairly easy. Replace the positive and the neutral with the new cable (make sure your polarity is right), and then wire the 3rd prong to the chassis.
Answer:
So, just buy a three prong plug and attach the existing wires like they are on the existing plug and add another wire for 3rd prong that will be attached to the chassis, right?

As far as I know, yes.
Answer:
Well I did a transplant. I opened it up and got rid of the old wire and plug and cut away at my power cable that went to my Peavey. I attached the new three prong plug and wires and it works like it should. Hopefully it'll keep me from ever getting shocked, hehe.

Should.
A couple shocks probably won't do much damage, but it depends on where the current goes through and whatnot. I've gotten quite a few of shocks from my Kalamazoo. This only happens when I'm around other equipment and come in contact with both the Kalamazoo and whatever else (mic, another guitar running through a different amp, etc..). So, hopefully after this week (after graduation, open house, and other stuff), I'll have enough time to fix it before it kills me.
Btw, its a backup amp. I rarely use it anymore. I might if I put a master volume on it so I can at least drive the preamp more. 5watts is too much to comfortably distort. The power caps more than likely need to be replaced as well... and I've never changed the tubes. Who knows how long they've been in there before I got it.
