Pa = 150W
This gridless GAMMATRON was developed so as not to infringe with the Lee de Forest patent (owner RCA) on the control grid. Instead, the plate close to the filament has influence on the electron flow towards the other plate (anode). Tube was advertised on back cover of the 1936 Jones Radio Handbook. Production was limited.
