[sdiy] Oberheim 4-voice plug/cord????

[Aaron Day]

Greetings.

Can anyone tell me the name of the type of jack that is used for an 
Obie 4 voice?

A friend has one on loan to ck out for a possible purchase but there is 
no power cord....

The jack is an oval shape and has 3 evenly spaced pins.

I'm here in Germany and I'd like to know the name of this type of 
jack/cord combo before I start asking in the supply shops.....


TIA,
