cleaning out the junk box:

large RF chokes, have 25 or so available.

I measured at one time, 5 mH L with 10 ohms R.

mulit-wound with 4 different sections, on ceramic form, with metal
mounts with holes separated by 3.125 inches.....

will send picture if interested.

for the price of a beer, and postage, one is yours...
make an offer for several.
