- Greetings, I'd like to know if their is a reliable way to test the emission of the power tubes we hams generally use. Tubes like CX800s, 8877s etc. without having to actually run them at full power i

- Howdy, Carl: I don't know. If there is, I'd like to hear about it. I suppose you might be able to notice a quicker drop in emission as you reduce the fil. voltage over the first few hundred hours, ma
