RE: grid resistors first stage of amp

CMiller combines with the grid to ground resistance to form a low pass pole. When the resistance is large and CMiller is comparatively large, F3 of the pole will be low enough to have an effect at the top of the AF band.

IMO, it's worth noting that some units with a large I/P grid to ground resistance have a pentode I/P stage. The list includes the H/K Cit. 2, the H/K Cit. 5, and the Dyna ST70. Accident? I think NOT.
