hellow there i have been looking at 30v supply and audioguro has stated that power supply has to drop about 89 watt at lower voltage and high amps has anyone thought of putting a voltage pre-regulater circuit at the bridge side of circuit that wiil cut down the voltage on main capacitor.this works by cutting voltage at main cap at say 7 volt above output this tracks voltage automatically.the circuit only consists of about 5 tansistors and a scr.will try and put drawing up i am new to this forum and am trying to find my way around.if there is any interest i will post?
