the knobs can be found at radio rallies or hamfest but much easier to change for a standard sized pot of the correct value.You could also at a pinch pad out the thin shaft by wrapping with electrical tape or similar.I used one with the split splines shaft type commonly found on all suppliers.?

I couldn't find the right volume knob too. So I ended up finding those wire connectors with two vertical screws. In the end, admittedly it is a bit ugly, but does well the job.

I saw somewhere a comment about the knobs. The encoder knob is

not a problem since it has a pretty much standard size shaft diameter.

However, the volume control shaft is smaller.

I've seen knobs on old clock radios that are this diameter size but

when I could not lay my hands on the right knob immediately, I began

to wonder what I could use in the meantime

I used a twist-on wirenut designed for large size wires. It is yellow

in color — colors denote splice size.

Twisting it on the shaft provides a usable knob for the volume control

knob. I suggest using some caution when putting the wirenut on the

shaft, though, no need for it to be gorilla tight. Make it tight enough

only to turn radio on and off. Also, if the wirenut "knob" is not straight

on the shaft, it is easy to move it to the proper position and make it

straight on the shaft and more what one would expect of a knob.

Sure, you can go to Mouser and sqqa ASelect parts to one's heart's content

but this "fix" allows immediate use even if waiting for that Mouser

package. For me, I want a usable radio and not a display model even

though I want it to look good. This temporary "fix: works for me.

Hope this helps someone.
