Blue Gas in Tubes - Why? Is it Bad?


My friend's Svetlana KT88s glow with blue gas. He says that it doesn't mean anything, but I'm not so sure. He claims that he has seen this in Svet KT88s from different sources, including Upscale Audio.

I have heard that companies like Audio Research screen out tubes for "gas". Is this the same thing?

Does this affect the life or the performance of the tube?

If you go to the AtmaSphere Owners Group (ASOG) website

you'll find out that if you are lucky enough to have the blue glow, you probably have a superior tube.

Plus, they just look so cool with the lights down at night.
