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

7805's are no more than 2A or so whether it's TO-220 or TO-3, just determines how much heat it can dump. Swapping and rewiring for a LM317 is a good idea but keep in mind that you will still heat thermal limits fast with lower voltage outputs.

This looks like a homemade versus a mass produced PSU? Not sure.

oh boy that ebay ad pisses me off, do not say "step down" and especially not "buck" with linear regulators...aaah... (though marking a SMPS with "LM317" as search bait is equally annoying.)
