Power Supply Unit to Moog Prodigy

Hi, I’m fresh into this forum and sorry if I approach the wrong forum. However, I have an early Moog Prodigy with serial number 3766X for which I lost the external power supply unit many years ago. The synths input power is based on a DIN 4-pole contact. The synth is running on 220 Volts. Does anyone have any tips on where I can buy such a power supply?

External power supply? Never saw a Moog Prodigy with an external power supply.

Me neither. Perhaps a mod?

Anyway, you need a standard +12V <=> GND <=> -12V power supply, identify the contacts of your external plug and solder an adapter.
