"Just as a side note, a very popular transmitter used by small, 250 watt, AM broadcast stations and made by Collins Radio company was a pair of 810s for the RF power amplifier and another pair for the modulator. Stations running this rig were easy to spot, they had a terrific sound."
The class A, A2, B and AB amps I figured worth learning where modulators and drivers are concerned. Most domestic vintage radios I have all use resistance capacity coupling. Once you look into AM modulation, though, differences in single end and power stages crop up. I came across push pull months ago but didn't really understand about watts and grid current.
