I *still* don't see how the "Equidrive" could affect even 60 Hz on the
primary. If you have just one cap in series with the primary,
wouldn't it block 60
Hz current just as well?
Is there some stray significant coupling to ground that I'm overlooking?

Yet again, I *still* don't understand why there's a difference with the
"Equidrive". The two caps are tied together by the primary, and the
transformer's
secondary completes the circuit.

Thanks for the anecdote!
Obviously, it must be *possible* to end up with a charged cap. I know
I'm sounding like a broken record, but I'd just like to know *why*?
