I'm desperately looking for a Hupfeld DEA electrical scheme drawing.
The old wires are missing.  It's not a simple circuit because of the
3-way input to the two-speed motor, two mercury switches, lots of
ceramic fuses, a pneumatic switch, and a paraphernalia of things.
Without the wiring drawing or a schema, it is going to be difficult
for anybody to fix it.

All the electric parts are in the back of the piano, so if any of you
have a DEA who could make me a drawing or could have the electric
schema it would be most appreciated.
