The EL86 is an output pentode with an anode dissipation of 12 Watts. The EL86 is designed for a higher anode current and lower anode voltage than the EL84. This would suit transformerless designs of the type called single ended push pull see data-sheet. It was also specified for use as a series regulator.
This exhibit was made by Philips in Holland
The notch in the anode shows the outer wire grid.
The thin glass tube envelope is 20 mm in diameter and, excluding the B9A base pins, is 70 mm tall.
