According to Bill Orr I think. Guru of home brew DIY amateur amps.

A "GG" grounded grid amplifier carrier cannot be fully modulated to 100%.

Unfortunately. No mention. What approximate percentage they can be modulated

to ? The Phantom 12 tube in my car. Dead keys 650 watts RMS into a 3/4 Wave

8 foot Fire-Stick. Lets say 620.watts It is not going to be 4 x 620 ? AM PEP

On SSB 16w PEP in. I get approx. 800-900 PEP on the RMS reading Coaxial Dynamics

watt meter.

I think it was Bill Orr. Been awhile. Still have that book 1973 edition.
