I only saw it once on one of my tubes but I can't even remember which one.

Eric check this listing.............
Looks like a picture of really young Vodka.....That must be an audio accessory...
From what I was reading this seems to be more common with pentodes and beam tetrodes than it is with triodes. Certain types of blue can mean gas and that the tube is no good, I guess if it is a cloudy blue coming from inside the plates. Glenn told me one of the National Union tubes I sent him for testing the amp started to glow blue from gas so I thought maybe blue was bad period for 45 tubes. Since what this Tung Sol seems to be doing is no big deal I'm just going to sit back and enjoy the light show.
This is fine it is just electrons that are missing the plate and hitting the glass
IF the amp is cranked up it will dance with the music sort of neat enjoy it.
The bad stuff is a pinkish blue that is inside the plate and sometimes the whole inside
of the tube will glow like this. Usually the tube draws lots of current when this happens.
The tube I said was bad most of the inside lit up and the cathode current meter pinned.
596 in disguise!!!!!!!!!!!!
I was helping out with your 596 hunt........
No but I will send two with the amp and they are cheep or you can put in a 5 volt rectifier.
Yes the Old chassis is like the WA6 and the new is about the same size as a WA22
Yes that The 5AU4 can be got for $3 and the GZ37 but they are expensive
Yes it has a smaller footprint and takes up less room.
I'm going to the doctor tomorrow.
They are removing my head.
So I have to fast for 24 hours.
No apple pie.
But lots of music until then.
I made this last night.
Steamed halibut over stir-fried vegetables.
Now I'm really torturing myself.
