Richard -
Did your electrometer show an unusually high charge that was left on the
toroid after it was shut down, say about 200 KV on a small coil? In my TCC
Guide I show how this could be checked without discharging the toroid but
your electrometer method would be better. How did you calibrate the
electrometer to read the high voltages at a distance? I have never done this
but I understand that others have.
