Default Broken 6L6WXT tube

Yesterday I accidentally tapped my 6L6WXT tube. I didn't know I broke it until 7 hours later when I went back in my dungeon... err I mean basement. The silvering on the top of the tube faded to a milky white color. How does that happen, does oxygen attack the silver coating? It stuck out like a sore thumb as I have a quad of them all together.

Regards,
Sal Brisindi

Sadly, that's exactly what happened. The getter flash is usually a mixture of barium and other metals, and when they oxidize they do turn white, indicating that your tube is no longer a "vacuum" tube.

My head is turning white too. I wonder if I'm oxidizing?

Yes, it means you're getting gassy, Brian.

How do I know this, hm?

Aloha,

Stay away from Taco Bell completely and stay alive. Every time you turn around, there's another story about E. Coli contaminated vegetables at T/B.

Not to mention the rats that took over the one in Greenwich Village NY a few weeks ago. But I can't stay away from them, even when home & my wife's away I make the dreaded spicy stuff that wakes you up in the morning too. I'm only being off topic here 'cause you guys started it, lol.
