A diode doubler using a toroid transformer, pair of diodes and a tuned

Is the type of distortion critical? How about a clipped/clamped
sinewave?

Yes and no. :-) A quantitative answer isn't possible since the
waveform must be described accurately in shape (or spectrum
analyzed) in order to determine the harmonic content. Suffice to say
that a square wave cannot be used with a passive diode doubler; all
the energy is contained in the short transition times and that is rarely
enough to be worth it.

Thanks, Len. A lot of good stuff to be considered here so I'll save it
for now and go through it later.....
