The E130L is a special quality pentode with a very high mutual conductance of 27.5 mA/V.
The design purpose was for wide-band amplifiers, series regulators and audio output. In the latter case a pair would be capable of producing 60 W in class AB
The makers identification and at the top the control grid heat radiating fins. The cathode tube is a flat rectangle and the bright structure within the anode is the beam plate used in place of the suppressor grid.
The wide glass tube envelope is 38 mm in diameter, and excluding the IO base pins is 111 mm tall.
Reference: Datasheet. Type E130L was first introduced in 1959.
