CAM3 cooled anode modulator triode
This is a liquid cooled anode triode suitable for use as a modulator. For water cooling a flow of 3 to 4 gallons per minute is required. The filament seals also require air cooling. See also CAT3
*: 10kV max when used in an amplifier to modulate high frequency currents
**: At Va=11kV, Vg=-1500
Markings indicate this valve has been repaired. Additionally, markings indicate that a filament voltage of 17.8V gives 7A emission at 90% saturation. The serial number is 1308.
