| Descripción |
This gridless triode was developed so as not to infringe with the Lee de Forest patent (owner RCA) on the control grid. Instead, a bar (or bars) fitted behind the filament has influence on the electron flow towards the plate(s).
In later production, the control electrode was a piece of sheet metal with serrating edges to enclose partially the filament.
