Thoriated Tungsten Filament power cycling
http://www.w0btu.com/miller-larson_effect.html
Why Their Life Is Shortened. When They Are Power-Cycled. How the Miller-Larson Effect affects power tube life and why on/off time is an important consideration.

Here's why that is so. Pub Date: December 2, 2011.
