From the estate of David Halley (WN9W) I have for sale an Astron RM-50M-BB Linear Power Supply. This is a rack-mount power supply rated at 37A, 13.8Vdc continuous, or 50A, 13.8Vdc peak. It has both a current and voltage meter. This supply appears as new, and I believe it to be no more than two or three years old. Asking $280 not including shipping. Please email if interested.
