Your only likely option would be to find a donor unit that has that switch. I believe it was used in several models.

I am going to attempt a repair I have a strip of .004" inch thick stainless steel shim stock that I've cut to .080" inch wide. This matches the inside strip of steel that rotates on the sprocket on the input selector switch. This will be drilled with a small diameter drill to match the cut outs in the original inside band that the teeth of the sprocket engage into. If this works then I just need to join this new section to the old section. I am not going to try to run the internal strip within the outside band. I may just cut small slots in the pvc outer jacket and use this as a guide. I will report in as I move along. I was thinking of soldering a 3 pole 5 Way function switch on the inut selector switch where the sprocket wheel is...then I would have to hardwire over to the circuit board.

Alps used to manufacture heaps of bowden cable operated switches. How many positions on the input rotary selector and how long is it? I may have one you can use.
made up new inner band with appropriate openings for sprocket teeth in selector switch to engage in to. Well my main man Rick in the model shop fab'd it up. Pretty precise work with ø.046" holes on .093" centers. Only have .017" left of material on either side of the .046" holes. the new section has been assembled in to the selector switch and it operates correctly.
just need to join the old section with the new section.

The input selector remote cable repair works. I did not slide the inner band inside the outer band. I am just using the flat PVC jacket. The jacket was about 1/2" short which allowed the inner band to move so I used a piece of shrink tubing to create a continuous outer jacket and the switch operates correctly.
I tested the amp with headphones and have sound.
I checked the transistor rail voltages and measured 55VDC.
But am not getting any sound....no sound...not even a hiss.
So I am going to check if the speaker relay Panasonic SSY99-1 Relay is allowing the output to pass to the speakers.
If I wanted to replace this relay with a new one any suggestions on alternative?
If I remove it off the board can the cover be removed and the contacts cleaned?

Removed from board. Cleaned and inspected. It didn't appear to be that dirty but will solder back in tonight.
The speaker switches are between the speaker select relay and the speakers so will check for continuity through these switches as well.
soldered speaker selection relay back on to the speaker impedance board. The amp is now operating. Sounds good cant wait to get a decent set of speakers on it. Really excited about this amp...considering it was a freebie.

Any luck? I am in the same boat with my unit.
I might have one if the same one is used on a V5 unit. Send me a dm.
