Samick Sytem 84

I received this mixer with no information or power supply. It was working when stored a number of years ago but the PSU (power supply) is missing & Samick has been no help. I need a pin-out & voltages for the PSU and/or a schematic.

Is this a small mixer? How many pins is the power connector? Look inside and follow the wiring from that connector - what does it connect to? If diodes, then chances are the powr was simply AC. We can assume certain things, like the mixer circuits probably ran on +/-15v. What voltage ratings are on the filter caps. Are there voltage regulators in there? If so what ones? KNowing thisw stuff would let us come up with a reasonable AC supply.

It's a rack mount 8 channel by 4 or 2 out. the PSU connector is a round screw-on 5-pin amphenol-type. I will pull it apart this week-end. Thanks for the quick answer.
