I have an old (1970s era) Russian designed (Polish) military surplus night vision scope. It is not working, but I think it could be fixed with a little brain power.
The entire setup consists of a power supply, the scope itself, and an infra-red light unit. The power supply is completely separate from the scope, and the scope has a mount for the IR light on top of it. The light & scope are connected to the power supply are connected by a long cable with three wires inside it. The intent is for the power supply to be worn on your belt, then the scope is less bulky to handle.
The power supply contains a 6 volt, rechargeable, lead acid battery. There are three pins that provide power to the cable and ultimately to the scope. One pin is negative, one pin provides 6v (for the IR light) and one pin provides ~400v for the power to the scope.
Well, my pin that should be supplying 400v is giving no power.
I took the power supply apart and looked for anything obvious, but found nothing visually out of the ordinary. There are several (about 10) components (I'm no expert, so I'll just call them capacitors, resistors, etc) in the unit, so I suppose one of these components has gone bad.
This leads me to a couple of questions. Is there a way to just rebuild the entire power supply with modern components so the bad pin will supply the required ~400 volts? Or... is there a way to possibly (with help from you guys) troubleshoot this thing down to the bad component that could be replaced or upgraded? I can provide pictures and take measurements with my meter, as required.
Thank you!
