John Freau, all,
 
What effect does different inductance values for different variable auto
transformers (Variacs) have on the circuit?  Since this is a LC resonant
circuit of sorts shouldn't variac inductance affect capacitance?  Also
motor inductance should play a role.  Seems like there may be multiple
dependant variables here.  Any work done in this area?
