Hello,
I built my Stereomour amplifier some time ago.
My 2A3 RCA NOS tubes glows differently.
One of them has a much more brighter blue glow than the other one.
To my ears both channels sound the same, but I shut the amp down quite shortly after seeing this - and I am now awaiting answer from you before turning it on again.
I`m new to tubes so I`m posting because I do not know if this is normal behavior on NOS tubes - or if somethings wrong....
All help will be appreciated

The blue glow is not a problem. Play away.

Cool !
Will put it on right away .
Just out of curiosity : what is causing the difference in the brightness of the blue light ?
Thanks.
