Hi,
I just repaired my dead SPX90 power supply and have had my confidence boosted. :-)  Now I am going to tackle my DX7S power supply which is in worse condition. I *think* I have most of the parts needed, but if the transformer is bad, then I'm out of luck. It's a special transformer for the switching supply.  

ANYWAY, ... has anyone dropped in a 3rd party supply?? If I fail to repair it, maybe there is an off the shelf +5v, +/-12v that will fit. Anyone done this?
