Chinese mini bias pots

[itsmejto]

Does anyone have info where one might get those little gold colored mini back wired bias pots used in most Chinese amps ? (25k)
Or if they are w/w or carbon etc and wattage rating ?
They are 1/2" dia. with 1/8" shaft dia, 3/8" mounting hole.

Looks like a Chinese copy of the old military style RV6 (or PCB mount RV8). Allen Bradley used to make them - I think PEC took them over from AB.

They're not very common in the USA any more, though you do find them in surplus places. A couple places to look:
