I understand there are no labels stating the supply voltage?
That power connector could be used for 120VAC before standarisation. Or it could need a custom external power supply.
At the back panel a space can be seen with 4 screws, it looks as it could have a power circuit behind. And in the internal photo, several wires come out of that area, below the SPOT LIGHT button.
Anyway, it is a full 120V power supply or just a voltage regulator?
Old Sony SEG2000 has a peculiar power supply. It uses one switching regulator for any of the three inputs (AC, external DC power supply or 12V batteries) and in the mains input there just is a step down transformer and 24V rectifier and filter. After that there comes the power selector (AC, ExtDC, BATT) and then the switching regulator.
