Default Yamaha C-4 input selector

The input selector on my Yamaha NS Series C-4 preamp has gone bad. The sound breaks up or fails altogether. Rotating through the inputs sometimes fixes the problem, but it always comes back.

I have no idea how to find the replacement part number, or a source for the part, since I don't think Yamaha makes them any more. Can anyone help me?

If I can't get the Yamaha part, does anyone know another rotary selector that would do the job just as well? Looks are not a consideration.

Thanks!

It may all depend on how many positions and decks the Yamaha uses.

I like the Grayhill selectors, and I use them. Contacts should be at least solid silver.

Are you sure its actually worn/gone bad or maybe just in need of a blast of deoxit?

It's been cleaned twice. It has 5 positions.

Thanks!

I've owned two of them. Once I pulled the switch out and re-clamped the solder points.

They are the usual kind of alps brand custom parts, they cannot be easily replaced by anything.

If any of you have ever taken apart a alps black beauty pot or the like, the failure point can sometimes be that the solder pins are 'clamped' to the plastic film substrate, which is alot like a little circuit board. the connection point is merely a press tight lug contact. So they sometimes need to be re-pressed. the switch needs to be pulled for this effort. There are no guarantees on this fix. As well, the contacts on the switch proper are done the same way and can be similarly fixed.

I was afraid of that. Any idea how I can find the part number and maybe track down a replacement?

Thanks.
