You say it shorted? How, H-K?
If this is indeed the case, then you have had something critical fail in the area to cause it to push the tube way beyond it's max ratings if it shorted that fast, like an open resistor or shorted capacitor.
You should be extra vigilant in looking at every related part and finding the cause before destroying another way WAY overpriced tube, thank you audiophiles very much!  |
Thats right it caused the new tube to short out immediately. I recapped everything leaving a couple of micas. There are a few resistors there too. C-115 if that shorted it would pull the grid voltage way up. I'll swap that one and check those resistors as there are a few there.
Unfortunately, I'm away from home for a couple of days at work and then I've got to study for my yearly recurrent training early next month. I'll only be able to dedicate a short amount of time at this for a couple weeks.
A 20$ 6CG7 gone in a flash...
