[sdiy] power transformer pointer ?

[Mountain Man]

Ohhhhhh  :(   That's disappointing.  I do hope I can find a replacement
transformer, I'd hate to have to ditch my Xpander because of lack of that
single part  :)    The specs of the transformer appear from the schematic and
manual as follows:  single primary winding that takes 13V at 30 Khz.  The
secondary is tapped, rectified and filtered to produce 2 +55V outputs, + and
- 12V, +5V (-5V is a feed off the -12V), 2 grounds, and 2 9VAC outputs, a
total of 9 outputs from the secondary.  Any idea of where to look for
something like this?   ANY pointers, no matter how vague, are welcome at this
point.

Thanks,
Elby
