We have prepared a list of approximately 100 Beam Power Pentodes that can be employed in the Power Amplifier stages of amateur radio transmitters
and tranceivers. As electron tube prices go through the roof, it more and more becomes a necessity to examine tubes already in hand, or inexpensively
obtainable, for possible substitutions in our treasured vintage radios.
This list will provide that needed information which includes base configuration, power capabilities, filament volts and amps, plate and screen power dissipation limits, etc.
