You're overlooking Dr. Miller. :>( The grid to ground resistor at the preamp's I/P combines with the CMiller of the 1st tube to form a low pass filter. A few MM carts., along with a few SUTs, interact badly with a 47 KOhm resistor and a 12AX7 section. As the grid to ground resistance rises, the number of "indigestion cases" rises.
