After years of research development and day-to-day manufacture with the EL519 series of pentode tubes Tim de Paravicini has come up with a new and exciting Triode configuration. Conventional triode connected pentodes have the second grid tied to the anode which results in a halfway compromise between a pentode and a triode. This neither has the efficiency of the pentode nor the linearity of the triode. Tim de Paravicinis Enhanced Triode Mode (ETM) goes one step further and creates a true highly linear triode from a robust pentode tube.
