One of these?
Looking onto the face of the plug, flat side down:
top-center: common ground
bottom left: 39.5V
bottom riht: 13.5V
Voltages measured unburdened
edit:
I thought them a little high ( for the specs on the sticker) so I hooked them up to a load. They stick exactly to their voltages, all the way up to 1.1Amp.
And on a scope, no wave or noise, nicely flatlining at all timebases.
I was expecting a badly flattened half-have, and maybe my load was showing peak rather then rms.
But none of that, there must be a proper lineair regulator in there, but then, why so much over spec? Would the regulator go off this much with age?
Anyway, you asked for the pinout, they are above.
