RE: How long did you run them in before hitting them with high voltage?

Hello,

I was theoretically very prepared before using the rectifiers. I did prewarm them for 30 minutes, observing the mercury vaporizing from the cathode and anode, and depositing to the bottom of the glass.

The rectifiers work fine. I was just curious about the random cloud flicker I have from random tubes at random times. Maybe it is the way they should work? I'm curious behind the physics behind it.
