Williams keyboard power transformer replacements?

[nosaj]

Hi I have a Williams Overture keyboard The power transformer has shorted. It has a 14v 3a tap and 2 7.5v 0.5a taps(of which only one is used.)
Having a hard time finding a replacement Anyone point me in the right direction?
If it were mine I'd cobble something in (which I am about to do to test out the rest of the keyboard) But I am not willing to send it back with out a proper transformer.

Thanks,
nosaj
