I was looking at the schematics (email me if you want the scans--I
found them on a Polish site in rather ugly self-extracting form) of
the 1960's Ionika EMP-1 organ (made in the DDR, but used throughout
the SSRs). Interesting design in its use of neon lamps and very
distinctive in tone.
At any rate the power supply transformer is switchable between 220
and 125 volts. What country used 125V, 50 Hz?
