First of,

It was not a very good idea to verify the radio workrd without at least electrolytics replace ent.
But now that it went well, good to know.

The power cord can be anything that fits of desirable length. Matter of preference.
If want to be near-authentic, check Tubes and more, Radio Daze.

Transformer wires could be replaced, but many prefer simply sliding heatshrinkable tubing over. Works well.

Volume pot can be opened and lubed/cleaned.
If it fails, Mark Oppat has some or repairs those that could be.

40uF is not a recommended value and could even exceed the allowed one for the rectifier tube (see the datasheet, it always is listed there). It is possible because the other cap also dried up, they compensated this way.
Replace both with the proper values.


Fixing the stud: use an L-bracket and screws/a rivet and a screw.
