Back in the day, in the sales & service arena at least, striving for perfect H linearity was never even a consideration. Even factory field reps (in our experience at least) never alluded to it. Just dip the cathode current for maximum life of the output tube, period. When dipped, there was no noticible non-linearity, even on the crosshatch pattern during setup.
