Subject: [AH] Need help with JP-6 power supply





I'm pretty sure the transformer is fried.  All of the fuses are ok but
there is no voltage
across the secondary winding.  Anyone have any idea what the specs for
the transformer in the JP-6 is?   I just got the service manual yesterday
and it just
has part numbers.  (Roland doesn't have a replacement either) I think I saw
on
there that one pair of outputs off the secondary winding was +/- 27 Volts
ac.

I guess another alternative is to replace the whole supply.
The Jp-6 supply is wide but not very tall.  (9x9x2.75?)
I looked in the mouser catalog and I didnt see anything that had enough
juice that would fit.

Any help or suggestions would be greatly appreciated.
