Well....not so fast. I found another 3at2 new in the box, put it in and the same thing happened. This time I could see the filiment glowing and it went out after about 15 minutes.
The inside of the tube was glowing blue so the plate is hot.
Whats going on here....is there an open in the filament supply turns on the flyback? Thats like 2 turns of pretty heavy high voltage wire how could that ever go open.....
