I have 866's in my 6CB5A amps. The filter is single stage L-C, and there is a big flash when the plate transformer gets power to its primary. They are Class A, PP so there is no variability to the observed glow...though selecting tubes with a larger shield to anode gap leaves a bit more of the blue cream floating around in the envelope...:) I would love to find some un-shielded globes.
