Best I can calculate it's about 15,000' will get you to 3165 ohms which is about 4 pounds of wire. Using less wire and adding resistors is not a good idea. It lessen the filtering and magnetic pull that the coil can develop.

I was down in the basement in my dad's

Vol 1-50 admiring the old set and trying to

Circa 1966
