CV1090 - the original 'micropup'
In this valve, the grid connection is at the top, filament at the bottom, and the anode is the centre block. The anode itself is a cylinder with fins attached for cooling. It has a thoriated tungsten filament consisting of a single helix.
In operation the valve must be mounted vertically. Forced air cooling is needed and the temperature of the anode block must not exceed 140C.
