I have a Polymoog model 203A serial number 4136 for sale. It is in need of a full restoration but is complete with no parts missing. I had got as far as restoring the power supply with all new capacitors/transistors/voltage regulators etc. The unit powered up and lit up but no sound. PSU voltages were stable but after a few minutes trying to fault find, a tantalum bead capacitor on the High Frequency Oscillator no.1 board started to smoke so powered down and added tantalum bead capacitors to the replacement list. I have collected a large amount of components to restore this unit including 3 rare DM8670N polycomm ic's. I have the two volumes of the service manual with full size schematics and the reliability improvement program service bulletin. The Polymoog has been stored in a custom flight case which is also included .I am selling because I do not have a workshop or the time to do this restoration. I am based in Dublin, Ireland so transport would have to be negotiated etc. Further information and photos on request.
