90’s-80’s Electrical shit i need help with (many questions)
This is a Promin Pn-3 gen 1 Night vision surveillance device i got it off ebay and i’ve decide i want to know how this works. The night vision tube is of the EP33 family i believe(i have its smaller cousin). In order to power these i know it needs crazy voltage, i don’t know how much or how quickly. I’m just going to make a list of my questions, its easier.
1. What image intensifier tube model does the PN-3 use?
2. What voltages does the PN-3 inverter output to the tube?
3. Does the PN-3 use a single HV output or multiple tube voltages?
4. Is the rubber-boot connection on the PN-3 the tube’s high-voltage anode connection?
5. Can the PN-3 inverter safely drive an EP33 image intensifier tube?
6. Has anyone successfully powered an EP33 using a PN-3 power supply?
7. Does the EP33 require the same voltage and polarity as the PN-3 tube?
8. Can the PN-3 inverter be tested unloaded without damage?
9. What measurements should I take with a multimeter before attempting a tube swap?
10. Is there a schematic or pinout available for the PN-3 power supply?
11. What are the functions of the major components on the PCB (transformer, coils, capacitors, etc.)?
I’m adding a comparison photo of a confirmed EP33 i do have for reference. Also i’m not experienced with these type of electronics i just know names and am still new to the general idea of this type of stuff
