I am probably too late in this thread,
but blue tube glow ist something nice and I like it.
Watch here:

What causes the blue glow?
What do you think?

"That's easy enough to do... how do you think my crew uncovered the
largest CP ring using Tor and I2P, which we promptly turned over to
the FBI? I discovered a way to uncover the IP addresses the I2P users were  
using, and a way of tracking Eepsites back to their IP addresses, then we  
figured out that we could DDOS a Tor IP address and modify Tor headers  
while checking whether a Tor hidden service was still up, then using  
process of elimination to pinpoint the IP address hosting that hidden  
service. It's not rocket science.

_The I2P community got all up in arms when I discussed on their forum how  
I was doing it, and that it'd be a good way of cleaning up I2P so it can  
get on with being a platform to research anonymous communication... my  
distinct impression was that the "anonymity
research platform" story was just a cover story to allow pervs to
trade CP._  (NOTE: admits to participating in what he "suspected" was a

Rather, ionised Oxygen and Nitrogen, the major components of air. 
It signifies a "soft bottle"  ("valve" or "VT" that has let air in).
That's what the silvery getter is for; when the getter is exhausted 
the valve is soft.

The Soviets continued with valve (vacuum tube) technology 
because valves have much greater resilience against atomic 
weapon electromagnetic pulses (EMP) than solid-state technology.

Blue, actually.  DAMHIK, IJD.  Also, the silvery 'getter'

  From other info in the thread it sounds like what used to be called a "starved amplifier". Read this:

True. Could also be gas. Even though gas usually comes from operating 
above rated temperatures, it's still possible that since "on" is hotter 
and "off" there still can be some out-gassing if the getter isn't 
working properly.

However, most likely is that there is some parts in the circuit running 
the tubes that are going bad. Does this only occur with certain brand 
new tubes? Tubeology is becoming sort of a lost art you know. Kind of 
like nobody knows how to make a decent mummy anymore.

For a "real" expert opinion ask HVAC. He has "superpowers" that include 
ESP that can home right in on what's wrong.
