This is my Heath HA-10 kilowatt amateur band RF power amplifier. It is capable of operating on all standard amateur frequencies between 3.5 and 30 mHz, and many frequencies in between the ham bands. It can amplify CW, AM or SSB signals of about 50 watts or more to a power level of 900 watts. An extra fan has been added on top of the amplifier for extra cooling since Rife/Bare operation is more severe than normal Amateur service. The output of the HA-10 goes to the Heath SA-2060A antenna tuner before being sent to the Rife / Bare tube.
