Default Re: An old dinosaur bench top power supply - help needed

Thanks redwire and thanks again RJ.

RJ - The regulator reads about 30V on one leg and nothing on the other, regardless of where the pot is set. So the 7805 is dead.

The browned resistor is for an LED and is working.

I will look into the LM317 conversion - Redwire I assume you are talking a regulator with three legs vs this current through the board 2 leg setup. Any recommendation of wire gauge? I figure I could pull the 7805 and solder jumper wires in the existing holes and run it to the back per your suggestion.
