Note
Designed specifically for use with for use with the HA-14 “KW Kompact” linear amplifier, which had no internal power supply. Similar in appearance to the HP-13 mobile power supply. The most obvious difference between the HP-13 and HP-14 is that the HP-14’s power connector is on the top of the unit as opposed to on the side.
The HP-14 is a fully solid-state switching power supply based on a proprietary potted toroidal type transformer.
Caution: Lethal voltages present when operating.
