"I will be providing a very high quality photocopy of the original
Simmons SDS-1000 Owner's Manual and Schematic Set. The set consists
of the Operating Manual which details the operation of the SDS-1000
and includes the schematic set for the module circuits, mixer, back
panel wiring, and power supply.
International buyers should contact me for additional postage costs,
prior to making payment. I would appreciate payment to be received
within 5 days after the auction closing. Please feel free to contact
me with any additional questions you may have.
