Hello all, Most of the schematics I've seen call for a 36 to 40 turn plate choke on a 1/2" to 1" form giving from 5 uH to 13 uH inductance. How critical is this value?

I have a plate choke with about 130 turns on a 7/8" Teflon (nylon?) rod with 86uH inductance and shows a resonant freq of 2.7 and 19.7mhz - both values well away from the desired 50 mhz.

My concern was voltage drop, but at 1 amp current, this is only 1 or 2 volts drop across 30 ft of #22 AWG wire Not enough to measure on a 3,000 volt line.

Will this excessive inductance cause issues other than voltage drop? It will be easy to remove wire to make only 40 turns if needed.

Thanks to all for the help that's been provided on this quest - I've sure learned a LOTS.
