The weight of the unit is about 18kg, which should preferably be handled by two persons.
Position the amplifier near the place where it will be used. You'll need an easy access to the command knobs and
indicator's area, as well as to the rear panel cabling.
No magnetic-field sensitive devices should be located next to the right side of the amplifier as its power transformer is
located there. It's best to position it to the right of your transceiver. No temperature sensitive devices should be located
above the exhaust hot air area, so don't push it under a shelf. You may prefer to use the bottom scales of both variable
capacitor knobs (TUNE and LOAD) if you install it on a shelf. DO NOT OBSTRUCT AIR INTAKE (rear panel) and
EXHAUST (top cover) areas of the amplifier. Keep a minimum distance of 10cm (4 inches) to the intake and 50cm (20
inches) to the exhaust.
2-4. Connections
Connection to your station must be accomplished in the order described below, before you apply mains voltage to the
amplifier.

Note that the grounding system may have to withstand currents over 10A with insignificant voltage drop on it. Therefore,
it may be necessary to improve it considerably, i.e. to become less resistive, with heavier leads and lower-resistive
ground path. The grounding leads should be at least 4mm2 (AWG 11 or SWG 13).
Fig.2-1 Connections
a) First, connect the ground stud of the amplifier (on the rear panel, marked GND) to the station's grounding system
(Fig.2-1).
b) Connect a coaxial cable with a PL-259 plug from the transceiver output to the amplifier rear panel RF INPUT socket.

If this is the first time you will use a power amplifier in your station, pay attention to the coaxial cable type from the
amplifier's output. It must handle the increased power safely, particularly on 10 and 6 meters bands. We recommend
you use RG213 or better. Check the same for the antenna selector and tuner as well as the antenna itself (especially
multi-band trap antennas).
c) Connect a coaxial cable from the amplifier output (on the rear panel, marked RF OUTPUT) with a PL-259 plug to the
antenna selector or tuner or to the antenna for the respective band.
d) Run a cable terminated in a Phono (RCA) connector from the transceiver socket providing "ground on transmit" to the
amplifier rear panel KEY-IN socket.
