[Amps] Want to use a knob with a 3/8" opening on a 1/4" shaft.

[Jack M. Henkle]

Hello fellow Amp enthusiasts,

 

 

I have two very nice 2 3/8” knobs that I want to use as band switches.  The
problem is that they are both meant to be used on a 3/8” shaft and the
actual shaft is ¼”.  Please share your knowledge so that I can use one of
these old knobs on a RS-85 switch.

Thanks,

 

Jack, W7JK
