One more question: the wire was definitely cloth covered and measures to be equivalent to about 35 AWG. This give a resistance of about .33 ohms per foot. The schematic from riders says this coil is 43 ohms. That would be about 130 feet of wire. That seems way high to my non EE mind. If it were actually 4.3 ohms (I cannot see a decimal point on the schematic - all other fractional ohm coils have a clear decimal point), that would mean about 13 feet of wire, which seems too little to me. Is 130 feet reasonable for a bobbin wound coil on the inside of the form? I've never unwound one, so I don't know!
