I'm on the final stages of getting a vintage bench power supply cleaned up and running, the last item being the replacement of it's Ne2 pilot lamp.

This method is called point-to-point construction.

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.
