Sansui 9090db parts?


Hi
I need a rotary selector switch for my Sansui 9090db receiver; my tech says the defective unit in my receiver can't be repaired.
Can anyone help?

Thanks

Mr. C in El Toro, Lake Forest does wonderful work. He restored a Marantz and Pioneer for me.
It's in the UK, and I don't have any experience with them, but there's this site:
