The EL34 is a much loved audio power valve with an anode dissipation of 25 Watts. References: Datasheet &. Type EL34 was first introduced in The EL34 is smaller in diameter and taller than the 6L6 and is capable of a higher plate voltage; factors that help give the EL34 its unique output stage properties.
