I'm on the final stages of getting a vintage bench power supply cleaned up and running. The last item, a Ne2 pilot lamp is now installed and operable.
Working on this stuff is a joy, so incredibly overbuilt, all hand wired, bundled and soldered.
All transistors are metal canned. Resistors are 200 or 300% above the expected disipation watts. The potentiometers are wire instead of a resistive surface.

i wonder if those wire wound pots last longer. i imagine they might. those modern carbon ones sure wear out way too damd fast to my way of thinking.
i remember that kind of construction still being standard when i was in high school. p.c. boards were mostly just coming in by the time i graduated in 66. oh they'd already been around for a while, but transistor radios were about the only things they were yet being used on, and those were phenolic i think it was called.
well fun with. i wish i had room to do things like that. one of these days when i move into a real apartment instead of the place where i am, which still has a sign that says motel on it, even though everyone living here has been for months if not years, and the street it's next to hasn't been a highway for decades.
