[R-390] OT: 50 Volt Regulator

[kenny]

Thanks guys for all your ideas and input...the idea of floating the 
regulator had never occured to me, that's a great idea. I will be 
studying the application notes on the LM723 and LM317 and build up a 
prototype and see how it goes.

The power supply I want to build is rather elaborate...it's for a linear 
amplifier project that I want to pursue. It's actually three supplies in 
one enclosure. I need 50volts @ 50amps peak, adjustable 38 to 50volts to 
set the bias and 12volts for the control circuitry. No point even 
thinking of starting the amp project until the power supply is sorted 
and if I make it adjustable over the full approx 40volt range of the 
regulator, the supply can be used for other things as well.

Kindest regards,

Ken
