Purple color in CRT

[Eric H]

Charles, this question has been gone over pretty thoroughly over at A.R.F.

The main consensus is if it checks good then it's good, the glow on the glass in normal, down inside the elements is Gassy and bad.
I've never seen a tube with purple inside the elements check good.

Some folks even think a purple glow on the surface of the glass indicates a very hard vacuum.

Jon, I'm not sure if your afraid it won't work or just looking for the Scientific answer to why it glows.

I'm quite confident it will function in your set, the Scientific answer will have to come from someone else I'm afraid.

Dammit Jim, I'm a Mechanic not a Scientist!

Thanks Eric your always a big help

I just wanted to know if the tube would still be good at performing, we will see when I am able to do a recap, but the fear factor that it was bad is cleared up thanks to you and the other forum members.

Have fun with that recap, especially the ones under the tuner. The lytics in the center of the chassis, you almost have to restuff the cans, no room to mount them underneath, too crammed in the first place.
