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.

From Wikipedia, the free encyclopedia. An EL34 vacuum tube manufactured by Mullard. Collection of Danko Tkalec HR. The EL34 is a thermionic valve or vacuum tube of the power pentode type.

Collection of Thomas Loidl A. Tesla; Praha, Bratislava etc. Collection of Antonio Bordini I. It has an international octal base indicated by the ‘3’ in the part number and is found mainly in the final output stages of audio amplification circuits and was designed to be suitable as a series regulator by virtue of its high permissible voltage between heater and cathode and other parameters.

However, Sylvania and possibly GE marketed a tube as 6CA7 which was not only in a markedly different ‘fat boy’ envelope, but used a beam forming plate much like a 6L6. RTT Franzis Examining the mica spacer on the top of the tube will confirm the lack of a suppressor grid.

According to the data sheets found in old vacuum tube reference manuals, a pair of EL34s with V plate voltage can produce 90 watts output in class Dataasheet in push—pull configuration.

EL34 End of forum contributions about this tube. Although power pentodes and beam tetrodes have some differences in their principles of operation the beam forming plates of the beam tetrode or fifth electrode 3rd grid of the pentode, both serving to hinder the return of unabsorbed electrons from the anode or plate to the 4th electrode 2nd grid and have some internal construction differences, they are functionally closely equivalent.

Collection of Howard Craven GB. EL34 EL34 Comparaison entre les distorsions. Erb Analysis by original leaflets. The EL34 was widely used in higher-powered audio amplifiers of the s and s, such as the very popular Dynaco Stereo 70 and the Leak TL25 mono and Stereo 60, and is also widely used in high-end guitar amplifiers because it is characterized by greater distortion considered desirable in this application at lower power than other octal tubes [ citation needed ] such as 6L6KT88 dl34
