HA-14 "Kompact Kilowatt"
The Heathkit HA-14 "Kompact Kilowatt" linear amplifier
was released in 1965, with optional HP-24 120/240Vac power supply and HP-14
12Vdc mobile power supply. Designed for either base or mobile operation,
the HA-14 has an IAS input of 1 KW PEP. Due to tube cooling considerations,
it is suitable only for SSB or brief CW operation while in a nominally
horizontal position.
The amplifier uses two 572B power tubes in parallel.
The matching power supplies are entirely solid state.
This HA-14 interior looks nice and clean. There is no obvious salt air
corrosion. The soldering appears marginally acceptable but should be
checked carefully. No components appear stressed
due to short leads, and there are no obvious modifications.

Observe the scorch marks on the top right of the case. They are
directly above the amplifier tubes. This HA-14 has been "run hot and
put away wet". Chances are the finals were overworked and
may be soft.
