Dynacord Eminence BassKing Favorit Echo etc

Inspired by Pekalit-19360-1, a knob used on old Dynacord amps, like BassKing I, Favorit, Eminence and tape-echo. Fits some Philips audio as well. You can use it as an replacement. The first design fits tight, I think it is too tight though. So the second version has some pointy surface inside to adapt to these old potentiometers a bit.
