Someone may have already commented on this John, (I haven't read all my mail
yet -sequential processing only).  This will not work for any power due to
the HV point in the center of the 1/2 wave driver breaking the system down
when real volts are in evidence.  Tesla notes this in his CSN.  He is getting
away with it because of his low input sauce.
