Jay and Hue have provided an excellent perspective as usual, and the 
idea of using a zener sounds like a good one for sets which (for 
example) have a strong AVC action.  The output voltage and load power 
demand is roughly halved as well when using half input, so any concern 
about overstressing the thermal envelope of the primary is a nebulous 
one.  From my severely limited experience, running a receiver dyno at 
half voltage for an hour with original load will show it to be stone 
cold, compared with full rated input and output which produces a frame 
that is slightly warm to the touch.
