Descripción

This gridless triode 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).
For marking purposes, the upper part of the glass bulb of the PLAV9 tubes was painted blue, at least for a while.
