Pete,
You're right. Those capacitors are used to provide capacitive reactance on
the line. The long lines, of course, serve as giant inductors. So, one
needs some giant capacitors. I have two such animals in my garage, provided
by WØAR, and they go with a gargantuan transformer for my "master B+" supply.
I have a two-step step start arrangement on the primary, because those big
caps will suck the guts out of a transformer before they get charged up. I
know it takes like 1/2 cycle of AC to do it, but man, what a half cycle!
If you want to drive over to see them, you can. I don't charge admission for
PVRC members. They are so large, I can't measure them but I estimate them at
250 mfd each, at least.
Needless to say, bleeder resistors are de regieur, Monsieur!
