Type 6BN6 is a late 1940s 'gated beam' valve in which a carefully formed electron sheet or beam is gated, by control elements into a series of pulses.
The data-sheet on 6BN6 & 6BN6 gives a detailed description of the valve and use and is in two parts. The data-sheet here gives the usual operating details.
The segmented electrode system. The cathode is on the left and the anode, within the screening box, on the right.
Looking at the back of the anode box.
The insulated heater can be seen on the lower right.
The thin glass tube envelope is 17 mm in diameter and, excluding the B7G base pins, is 57 mm tall.
References: Data-sheet & Brian Cuff. Type 6BN6 was first introduced in 1965.
