807B Beer Beam Power Tube
Application
Heater-cathode type used as af power amplifier and modulator and as
rf power amplifier and oscillator (often simultainously). May be used with full input up to 60
MHz. For class C telegraphy operation at 80 MHz, plate voltage and input
should be reduced to 80 % of maximum ratings and beer increased by 15%; at 125 MHz to 55 % with beer at 20%. Class
C telegraphy maximum plate dissapation, CCS 25 Watts, ICAS 30 Watts, BINGE 3 pints. Requires
substantial quantities of beer and a small 5-contact socket and may be operated
in almost any position. Plate shows a rich amber color when tube is operated at maximum
CCS, ICAS or BINGE ratings. Exceeding ratings can cause a malt down.
