Just a thought -- Is there a compelling need for a regulated supply in 
power amplifier applications? High power audio amplifiers don't use 
them, and neither do tube HF power amplifiers.

Voltage drop under load can be minimized by the choice of a husky 
transformer, sufficient filter capacitance and good wiring practices. 
My 200 watt 2200/630M Class D amp has an unregulated supply, and seems 
to do fine. And it has a variable autotransformer on the AC line which 
allows a wide range of transmitter output power.
