I've given a lot of thought about the 45V system originally installed in the Super Graphics. The one question is why they went to the 2-22½ battery arrangement, when the Speeds had the low voltage solenoid that obviously worked. I understand why they did it, but now 60 years later it's a mess. And here's where my lack of electronic circuit design knowledge leaves me able to dream up the concept of the wheel, but no ability to actually design it. Here's what I know: The battery bay on a Super could hold 4-AAA batteries in an easily fabricated pack. Certainly in this day of modern electronics there must a circuit design to kick that 6V up to the needed voltage to trip the shutter with the pre-existing lensboard solenoid. And this circuit should be able to be contained in the same space after removal of the camera body's factory capacitors and diodes and such. A further advantage being that it would be a true open circuit when the red button is not depressed, rather than depending on capacitors not leaking and running down the expensive batteries when the camera is not being used. I do not know what the voltage at the solenoid contacts was with the original wiring, but certainly there must be a way to do this, if anybody knows anything about designing such a circuit.
