Hi All,

I looked at the input current and capacitor current with my controller 
setup at about 1/4 turn on the variac.  This is where it "growls" the best ;-))

The wave forms are stunning!  Here is the AC input:

and the capacitor current:

Those 30 amps spikes are a combination of "everything".  But they seem to 
be high enough in frequency so the varaic does not saturate.  They just 
help it to growl ;-))

I am just running a 10 amp powerstat and 140uF of capacitance which seems 
to work well with both my motors.  Here are some exciting pictures of the 
lab setup :-D
