The 19AXP4 filament glows nicely and there are no shorts, but the emissions are 0. Absolutely no signs of life.
A likely cause is an open cathode. Twice before I've encountered this and been able to reweld it with my Sencore CR-70.
I was getting ready to try rewelding the cathode by whacking the neck while holding the remove shorts button when it came back to life.
Maybe I scared it
The needle swings erratically at times and I wouldn't be surprised it it dies again, but I figure it's good enough to try firing the set up.
Unfortunately, I got nothing. That red shaft at the bottom (circuit breaker?) feels loose and might be broken
