Does anyone have test data for a Raytheon Type B-H tube? Data for Hickok 6000, 800, or 752 would be acceptable.
Thanks!
Matthew

No tube tester data but I can tell you something about BH. Plates are on pins #1 and #4, cathode pin #2. This is different from most rectifiers. It's a gas rectifier similar to 0Z4 but 4 pin base. Voltage drop is 90 volts.
You could put positive voltage on pin #1 and draw current, through a resistor, from pin #2. Since the tube has a high voltage drop need more than 100 volts. If you get current the BH is usable.
