Power Pentodes for RF Power Amplifiers

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.

Our tube data library contains specification sheets on 1000's of power, industrial and receiving tubes. Should you need specification sheets on a particular tube, we can make a copy from the original (usually 2 to 5 pages) for $2 and an SASE, $3 if no SASE. If for some odd reason we don't have the sheets you request, the $2 is returned in the SASE. You can; however, check with us first via E-Mail at: radyojo@angelfire.com or swanradio@xoommail.com .
