HA-20 6-Meter Linear Amplifier

A perfect style and performance mate for the Heathkit HX-30 SSB Transmitter! The HA-20 Linear AMplifier provides the extra power you need for reliable communication during band openings. Efficient design requires just 2.5 to 10 watts P.E.P. driving power for a full 70-watts P.E.P. output to the antenna. Its tuned-grid input permits a variety of drive power levels and the tuned, link-coupled output easily matches any 50 to 75 ohm coaxial transmission line. Complete RF shielding minimizes TV interference and adds high circuit stability for consistently fine performance. THe push-pull 6146 final amplifiers are neutralized for maximum stability and fan forced-air cooled for long tube life. Panel metering of final grid current, plate current, and relative power output is also featured.
