This exhibit is a valve amplifier built into a metal can on a B9G base. Within the can is an amplifier circuit built around three CV466 miniature pentode RF valves.
The aluminium can that houses the amplifier.
The circuit is built between two ends. The valve pin heater at one end and a paxolin disc at the top end.
The valves have spring metal clips around them that touch the outer metal can to assist cooling. The can additionally has two sets of holes at the level of the top and bottom of the valves also to assist cooling. The ring around the can is in fact a plastic ring.
Two views of the heatsink clips that surround the valves and conduct heat to the outer can.
The wide metal tube envelope is 33 mm in diameter, and excluding the B9G base pins is 77 mm tall.
Reference: Datasheet. Type CV466 was first introduced in 1950.
