John Cooper7755 Homer DrBeaumont, TX 77708 I'll take whatever you want to send. Nothing is too big too small too old. Thanks!

Sorry i lost track of our earlier comunication. Need any large diodes? Probably 500-1000 volts, 50-75 amps. I can spare 4, enough to make a full wave. I also have some scrap copper .050" thick x 3.5" wide x 6-18" random lengths. Got to down size to make room for other interests.

I'm using THHN 14awg now which is working good for me though too. So unless you just absolutely have no use for it I will try it out.
