I have 1 200A4, 1 200B1, 2 200B2, 1 200B4, and 2 400A5 PA amps. I am tired of sometimes stepping up to the mike and getting bit. I've seen that Kustom Deb has the info for grounding these bad boys. I need you Deb!! Thanks Bob!!

The simplest way to way to change the cords is to go out and buy a 16 guage 25' grounded extension cord with molded ends. Cut off the female end and strip it back and solder the black and white wires to the power switch on the same terminals the originals were. Then use a ring terminal on the green ground wire and find a screw on the back of the cabinet and install the ring under the nut. You will need a crimping tool for the ring terminal. You will be able to use the strain relief over. Just squeeze the plastic with a pliers to compress the old cord to remove the relief. Then reverse the process for the new cord. The extension cord is cheaper than buying cord and a cord cap.

Because I am argumentative old cuss, I will only disagree on 2 points. First My K100 has a 16/3 cord, green because the rig is cascade, and I had very little trouble getting it in the strain relief. The cord is na SJ type of cable which in National Electrical Code speak, is a junior cable. Hence the J. That means the overall diameter is smaller than that of am SO type neoprene cord. Junior cable is considered to be light duty. Heavy duty means it can be run over by fork lifts and that sort of thing. Now the second point is that I am an electrician, and have been one for 25 years. I use a professional quality dimple type crimper, a Thomas and Betts. I use only T&B or Panduit solderless connectors and it would require a ripping of the conductors to remove the connector. The hardware store or Radio Shack terminals and crimpers are marginal for sure. Soldering does work VERY well, but I don't carry a hot soldering iron in my back pocket while I terminate control panels so the solderless had BETTER work.

P.S. I am always this grumpy unless I'm playing loud.

Because the current of any Kustom amp will not exceed 3 amps or so, a 16/3 cord is more than ample The actual rating of 16 guage cord is 8 amps, more than enough for the largest Kustom.
