Ground prong broken off. How to replace?

[Burlington]

I don't trust those DIY plug ends. Plus they look like ****.

If you do it correctly they are fine. If you think it will fail, you can always use some heat shrink to stiffen the connection.

I would just replace the wall plug, not the whole cord assembly. There's simply no good reason to go to the hassle of pulling the chassis from the cabinet, extracting the cord from the bushing/strain relief, sourcing a new cord, attaching the wires to the correct terminals (do you have a big enough soldering iron?), reinstalling the bushing/strain relief without crimping the cord, and checking it out. Instead get a good plug, carefully trim the ends of the wires in the cable, connect the black wire to the brass terminal, the white wire to the silver-colored terminal, and the green wire to the ground terminal. Make sure there aren't any loose strands of any of the wires peeking out from the terminal connectors, and seal the plug. Maybe once a year when you're tightening all the screws on the rest of your rig, check the inside of the plug.

Capacitor discharge shouldn't be an issue as long as you're not poking around inside the chassis. If you do opt for DIY replacement of the entire cord as FloydEye and maches suggest, then you do need to be aware of caps, and if you don't know about that, then take it to an amp tech.

Thanks, thats exactly what I needed to know. I'll stop by either home depot or the electronics store on my lunch and pick one up.

WHAT?
You unplug your TV from the wall and it still turns on?
You're car restarts after you turn it off only if the battery is in good condition and hold a charge.
The only charge would maybe be a static charge and a little shock. ..... But no stored energy.
......

Jesus Christ man, don't be giving out advice on stuff like this if you have no idea what you are talking about. Someone might be foolish enough to listen to you.

Anyway, if you don't open it up and start messing around inside you will be fine. Just replace the plug.

If you do start messing around inside you need to discharge the capacitors in the power supply first. If you don't know what I'm talking about do some research or get help before you open the thing up.

Agreed. Amps, TVs, and other appliances can hold a charge for YEARS inside. And it could be enough to kill you in a split second.

I remembered learning about this awhile back with either car stereo stuff or home receiver stuff. I definitely know enough to disregard the "if its turned off i can't hurt you" statement.

Thanks for all the help guys.

CRT TV's are especially bad due the high voltage caps used for "quick turn on" of the tube.

Do amps have some kind of capacitors that will store energy and discharge it after its unplugged?.

Only on the load side of the power transformer, not on the supply side.

I took the opportunity to add some tech flex/sleeving to the power cable. Everything works great.

JTE is right - this isn't major enough to justify pulling the AC cord out and replacing it.

Personally I'd just replace the AC plug. There are plenty of good ones out there and TONS of Internet sites that tell you how to wire them safely.

My condolences to the moron who clipped off the ground plug. Hope he's still alive but hasn't reproduced.

I know this is an old thread but I had a gig yesterday and my drummer stepped on my Ampeg amp plug and broke the prong. It's an attached cord and not one of the modern switchable ones. I'm going to have to cut the head off and fix it.......

Shouldn’t be a problem…just follow the instructions to a “T”. I’ve always considered plug-ends to be sacrificial which is why they sell UL-listed replacements.

This just happened to my shop vac and it was a pretty simple fix replacing just the plug end. I just realized yesterday that my old Fender bass amp, which I use to power our drummer, also is missing the prong. So I have 2 little projects.....
