My question has to do mostly with battery life. The Super Graphic has no on/off switch. So that means it is entirely dependent on capacitor quality to keep the batteries from being bled down in a short time. Speaking as a radio hobbyist, I don't believe I've ever seen a capacitor I would trust to have zero leakage. I have cut electrolytic caps open. I understand their construction of 2 rolled up foils separated by paper. I understand all that. But capacitors leak anyway, even brand new. All that said, I would very much like to order a set off 22 1/2 V batteries for my Graphic, but I don't want to install them, just to use the camera occasionally and have them to be dead the next time. I'm perfectly willing to open up the camera and install brand new capacitors. But what good would it do? As soon as I put 2 new batteries in the camera, the caps will charge up and bleed down slowly till the batteries are dead. That's my thinking. Unless someone would care to enlighten me. Thank you.
