[Collins] Regulating the 140 vdc supply line....correction 75S3receiver

[Bob Spooner]

Smith,

If you do regulate the supply line, I would suggest using an integrated
circuit regulator rather than a zener diode circuit. IC regulators are more
efficient, and that would be easier on the power supply.
