Hello:

I think at the <1 kv voltages on 6146x's, it's a gas problem, or
whatever other low (relative) voltage problems prevail in tubes.

In moderately hv tubes (say 3-5 kV), like 4-400, 3-500, etc, I've been
told by a now deceased tube engineer that the tube glass often
fluoresces blue at higher voltages...so I guess it depends where you see
it. I have seen 4-400's and a 3-400 runnig about 4000 VDC have blue
glowing glass, but it was nowhere near the grid. filament etc. It was up
near the anode rod and cooler.
