I've noticed on several amps and tuners etc that there's a weight inside the case, mounted to the shaft. It seems to give a really nice heft to the control
Has anyone used this idea or had any experience?

Most certainly this is a flywheel at the tuning knob's shaft. Never seen this at potentiometers etc.

I had seen in some old tube radios, a plumb (Lead) wheel inside the receiver, it made the short wave (In these era) tuning easier.
Ive found loads on the tuning section of old radios and tuners. They were linked on the string that moved the needle.
But I've had two, that I can remember, on amps I've tinkered with. Directly connected to the shaft. I think they were in large radiogram cabinets
Should make the pot feel nice and 'weighty' I guess?

Like the others, I have only seen this on a tuning control. The aim was mainly functional: you can spin the dial and it will then travel for a while using inertia.
Good tuning controls are MULTI-turn. If you want to spin to the far end of the dial, some flywheel effect is nice.
Volume (tone, input) knobs are not multi-turn, and generally you don't want to spin to the other end all that fast.

and you want it to stop when it reaches end of travel!
I think it's more viscous damping rather than weight you are looking for - think slow close lavatory seats, cassette door lids (if you remember cassettes?).
Something like this might suit -
FDT-47 | ACE Rotary Damper FDT-47 +50degC -10degC 2+-0.3nm Rotary Damper | ACE

Would make it feel weighty without a doubt 🙄 as for nice...?...how does that work? I would have thought it would make it harder to adjust accurately due to added inertia. Sorry, makes no sense to me
Here is a vendor that makes weighted knobs for various amateur radios. I am using one on one of my radios and like it better than the factory knob. Rather pricey though.

Folks:
I purchased a 54mm diameter stainless steel knob from Viljo Marrandi (Viljo Marrandi art and engraving – Handmade art) for a preamp project that has unfortunately stalled. The price, including shipping from the EU to the US, was well under $50. His knob is beautiful (please don't misinterpret me), weighs about a pound and I look forward to using it in a preamp soon.
A custom-made knob could be an excellent alternative, no?
Regards,
Scott
