I got Technics 323 tuner amp, which is lacking a volume pot. It has
balance adjustment on the same knob, too. The knob came with it, it has
a "head" and "sleeve" which both have the same radius, and have no
space between them.

Concentric pots. The volume one is a pair of pots, on cheaper gear with a
power switch on back. VERY hard to find a replacement these days - I
remember Centralab used to advertise a system where you could snap a
combination of parts together to make up one of these.

They seem to be long gone now. Good luck. Even if you find one, if used /
eBay it may be in poor shape.
