Voltage selector rare??

Anyone know where I can get one of these voltage selectors from? It has YKS11-0002 by JALCO on it.
I tried looking up the number but there's next to nothing about it and I think the company no longer exists?
It's out of a Pioneer A-656 Home theatre amplifier.
It's the only thing stopping it working "hopefully" everything else checks out fine as it doesn't look like it was set to 110v and plugged into 240v

Any help would be greatly appreciated 🙂

You could/should have made pictures with the wiring or do you have a schematic? It is easy, normally it are the 115V windings in series and sometimes an extra 240V tap as well. You don’t bypass anything, you solder the available primary windings in series. That may be a challenge when there is a lot of wiring to tidy up.

The positive thing of leaving the switch out is that one can not make a voltage mistake anymore 😉
