Sorry, for purposes of simplicity I omitted the crossover.  The zeners 
(+resistor on one side) would go in between the step-up transformer 
(300 ohm side) and the crossover network - which on the input side has 
an almost infinite DC resistance because of the L/C circuit - cap 
values range from 2.7 to 12.4 microfarads (and maybe I do need to up 
them, they're marked 100V not the 150V I had originally read).  I'll 
experiment with and without the resistors - I've got a few zeners to 
burn, after all.
