Putting a meter lead up to the floating grid turns the tube on instantly, so that makes sense. The question is, what can I do to make it turn off??? (besides switching off the primary)
I tried unplugging the 6J7G. Same response, except that it cannot be turned on remotely. Activating the thyratron remotely and then unplugging the 6J7G, the thyratron still remains on. I think when activated, both the stepping and holding relays are magnetized continuously.
A few hours later, I tried fiddling around with it some more. For no reason at all, the stepper is now trying to work with the mystery control. Sometimes the thyratron gets stuck, but sometimes in turns off like it should. Who knows how long this will last?
