The power adapter for the Votrax unit has the approximate specifications:
(from what I have gathered from photographs) was rated a 17VAC rms CT @ 1A and 20V DC @ 0.5A.
The 20V "DC" came about from two diodes that where contained in it ( no filter caps in it), from a 30V CT winding (15V aside) so the peak of DC pulsed full wave rectified voltage was about 15 x 1.4 or around 20 to 21V. The filter capacitors are contained in the Votrax unit.
It uses a 5 pin din plug. Where the 5 pins are arranged closely on a semi-circle of no more than 180 degrees.
I had thought these adapters were unique to the Votrax unit, but one day, looking on ebay I saw an adapter with the basic same specs & connector. I think it was for a fairly common vintage computer console, but silly me, I did not write down the model number and cannot recall what model/brand it was to search it again.
Does an adapter like this for some vintage computer model ring any bells ?
