I am new to this group; thank you for the wealth of information here.
I am seeking a schematic for the PianoDisc PDS-32.  I recently received
a piano with this system installed, but the power supply board on the
unit is burned up (the section on the board is charred, a resistor is
burned open and the fuse is blown).  I don't know if any other part of
the system is damaged as well.

The box between the main unit and the solenoid system powers up, but
I am not sure what the best way is to test this section.  I cannot
afford to replace the system with a current model as that is way beyond
my budget, but I have no fear of anything electronic.

I could replace the power supply with something completely different
that supplies the correct voltages to the corresponding pins, but
I don't know what is needed.  It might be easier to just replace the
main unit, but I don't seem to find any units available at this time.
Any comments or thoughts of how to proceed are welcome.

Thanks,
