Trying to match small AC transformer - 240V primary 12.8V secondary

**Again: The Yamaha distributor in Australia is pretty good.

Is there just the one for all Yamaha products? In the UK I found the one
which dealt with their pro audio fine but not the one for computer stuff.
It was some time ago when CDW was newish and expensive. But I've got a
long memory. ;-)
