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.

Plastic transistor packages and resistive film pots might not have been widely available at a reasonable price in the mid-60s.
Does it have aluminum wires or copper?
It's good to have your fiddly bits rated 2 - 3 times greater in power dissipation than you are expecting in case you do something silly, wire something incorrectly that you connect to it, or there's a problem on the mains line.
What is the object to the far right side, outside the case near the transformer? There's a better shot of it in your vertical photo. A capacitor? Fuse? Flux capacitor?
It's nice to see someone tinkering with these old devices and getting them to work again.
I'm tinkering with your project's child or grandchild, an op-amp controlled variable power supply.
