[Amps] [AMPS] 3-500z "glow blue"

Donald Chester, K4KYV has mentioned sometimes the blue glow is not due 
to a tube being gassy, but to impurities...
Here is a nice webpage about the blue glow..

If I key down with my 4-1000A amp tuned up, I can see a faint blue glow 
around
the glass, looking from above - but I thought that was normal
