CV345 is a power output valve designed for the demanding use as a series pass valve in stabilised power supplies. The prototype was the VX6044.
The heavy demands placed on valves used as control elements in regulator circuits makes it vital that the ratings are not exceeded.
The anode has two ribs pressed into the sheet metal. Other maker's products have a more rippled look to the anode.
The copper control grid supports are topped with heat radiating fins.
The classic envelope is 50 mm in diameter, and excluding the IO base pins, is 123 mm tall.
