Kevin,
 
When I said 'disconnecting the inverter' I meant isolating it.  If the C-W
multiplier requires an impedance in place of the removed inverter then perhaps
that could be switched in with a suitable vacuum relay or something.  I will
defer to your own claimed considerable experience in this matter.  Thanx for
the input.
