What I remember Bill saying about this had to do with using a GG stage to amplify a carrier, and then applying high-level modulated B+ to the plate circuit. This is the classic "high-level modulation" layout.

Pretty sure he wasn't discussing the use of G-G as a linear amplifier for a signal that's already been modulated. 100% modulation is no problem for that setup.

If you look at the schematic for any old-school tube-type AM transmitter, you find two things:

It's Class C

The cathode is grounded.

Like the final stage in a Tram or Browning radio.
