That's called a turret. Guitar amplifier people use a lot of them for hard wiring parts.

The turrets remind me of the guitar amp I built with one of my sons ...

We used to use turret boards for building hi-fi audio amplifiers, now it's mostly guitar amps
that are built with them, for ruggedness and repairs.

Yeah that's right, a turret. I think I actually have some somewhere.

I did find some turrets and of course they were too large. FWIW, I ended up just filling the pad with solder as suggested by others. Worked beautifully. Thanks for the help with with these small details. The amp is getting close

No coax love?
RG174?

+1 I have had great luck with RG-174. It’s nice and thin and seems to provide good shielding. Use a good brand like Amphenol. These are great for soldering to panel feed through RCAs back to amp inputs. They can even be made to fit onto Molex KK or JST 2-pin crimped connectors. A 100ft spool is enough for almost half a lifetime of amp building.

Here is an example of a 3pin Molex KK input jack going to two RG-172 each going to a 2-pin Molex KK.

Hasn‘t the rg-174 a steel-copper core?
I‘d recommend mogami 2520: awg 28 copper, very thin, very flexible!
