And you've made them before.Tubes are not totally linear.
The average current draw changes as the dynamics of the music changes.
It's not 12.5ms or 50ms we need to look at.
In a song in 4/4 time with 120 beats per minute and the band gets cooking for 2 measures.....60sec / 120 = .5sec per beat. 4 beats per measure.
2 measures, 8 beats, 4 seconds.
So now the DCR of a supply does comes into play, not just the impedance.
The AVERAGE current has increased and that increase is sustained for FOUR seconds!!!
This is totally different than Jeff and Dennis trying to say that DCR matters in an idealized circuit with idealized, perfectly linear tubes where the AVERAGE current does not change.
It is now a conversation that can be had in a logical, reasonable way without throwing out known science.
