1960s Power supply refurb
Bought this locally from facebook marketplace. Decided I'd rather refurb it than buy a chinese box. Ebay'd the voltmeters and ammeter. Modded the middle one so the silver switch selects either 3.3v or 5v. Bought cloth wrapped wire for the aesthetics. The old Radio Shack Electronics Learning Lab was mine from years ago. Deleted the batteries and hard wired the breadboard to the power/ground bolts.
