Need help obtaining a part...Pioneer AKX-507 line switch

Greetings all,

It's been while since I been on DIYA...
I've run a couple of Pioneer repair threads over on AK.

I just purchased an 80's Pioneer pre-Elite A-77X (S/G multi voltage model) as a backup to the one I purchased in Europe when I was in the Army in Berlin.

The first thing I noticed was that the voltage line selector switch on the back of the unit was broken

The part number is AKX-507. That part seems to be "unobtainium" here in the States. This place in England apparently has the part but is unwilling to ship to the U.S.

Can anybody lend a hand?

Thanks for looking.
