The afterburner line of amps was made by Hygain in Lincoln Nebraska.If its the one I have listed here in my manual these would be the specs for it........
Primary power.......115 vac
Freq coverage........25-40 mhz
Types of emission...am,fm,cw,ssb,dsb
Power output(slightly less at 50 mhz)
80 watts carrier cw/fm
60 watts am/100%modulation
100 watts ssb/dsb (amatuer service)
Receive amplifier...20 db gain
Power required to key.......1 watt
Max drive(unmodulated carrier and fm).15 watts
(amplitude modulated carrier)............3.5 watts
(amplitude modualted peak)...............14 watts pep
Harmonic supression.........................more than 60db
Input impedance(unbalanced) 50 ohms nominal
VSWR less than 2:1 25-54mhz
Output impedance (unbalanced) 50 ohms nominal
adjustable 40-70 ohms nonreactive
Switching .............automatic by rf sensing network
Tube and semiconductor complement......2 tubes,2 transistors
9 diodes, 1 integrated circuit.
