This EL84 has the ERA logo of Edicron. The EL84 output pentode was introduced by Mullard in 1954. To demonstrate its use and quality the Mullard applications lab produced an amplifier design. The now classic 5-10 high quality audio amplifier.
Looking through the end wall of the anode the grids can be seen as all wire, thus this is a true pentode.
The thin glass tube envelope is 20 mm in diameter and, excluding the B9A base pins, is 70 mm tall.
