But only to a point, where HV regulation falls apart from insufficient power driving the flyback. There were certain 25" Admirals in particular, using 6KD6 and that crazy pulse-feedback HV regulation. Cathode current would spike to over 400 ma. on bright scenes, and we played with G2 voltage and different damper cap values, to get K current within reason consistent with stable regulation and width. We informed the customers of the modding, and told them to holler if it didn't hold up, but it held up OK.
