    is an amp power chord fixable or changeable? I got a sweet Ampeg b-100r, but the previous owner get rid of the grounded piece of the power cord and it makes a little noise, I guess with the normal grounded 3 piece cord it will be fine

    Yes, just rewire it from the initial connections on the amp.

    Then take it to a tech. Shouldn't be expensive. Tinkering with mains voltage can be lethal.

    Doesn't have to be an amp tech, every electrician should be able to fix it.

    so it's fine up to the actual plug?

    anybody with a clue about these things could snip that plug off and install a new one from the hardware store, easy peasy.

    You can buy a heavy duty, but cheap three prong plug at any Home Depot, Lowes, or any Ace or other hardware store. I've replaced these numerous times over the years. There's NO danger if you simply cut the old plug off, and strip back the insulation on the wires. The terminals the wires will go to are screw type. Any handyman could do it for 10 bucks, if you cannot. It is exactly the same operation for any appliance that uses a standard 110 v. plug! There is a black, white and green wire- ask someone in the store where they go on the new plug you just bought.
    Like repairing the end on a 1/4" cable, same thing. And, of course- make sure the plug is not still connected to the wall when you cut it off!

    A complete new a/c cord can also be installed in the amp itself. If the cable is fine up to the plug, then it's an easy fix, as described above.

    LHbassist is right. If you carried your B100R into most any Ace hardware store and bought a replacement grounded plug, they'd prolly instal it if you asked. (for free) Most of those Ace hardware store guys will go out of their way to be helpful like that!

    I would like to add that you should purchase the best quality plug you can find. The "Hospital" style of plug is much better than the common rubber types.

    Sounds like you only need to replace the plug, the very best are made by Hubbell...

    Personally, I found the original cord too stiff, so I replaced the entire cord with a better quality, more flexible one. Not a tough job apart from sgueezing the strain relief in & out.

    Good luck!

    Most replacement plugs are color coded. Black wire to the brass colored screw, white wire to the silver colored screw, and green wire to the green colored screw.
