Information
Product Description
The
Amp Supply LK 400.500 series linear power amplifiers are
compact 160-15 meter MF/HF amplifiers of modern design. The
series provides the amateur operator with a choice of power
output levels and features consistent with their specific
operating requirements. Each
LK 400.500 series
Amplifier
uses the powerful 3-500Z triode tube(s) in a grounded grid
configuration Class AB2. The
LK 400.500 series amplifiers
are high performance pieces of equipment and are engineered
conservatively with American components and ingenuity.
Every
LK 400.500 series MF/HF linear
Amplifier is field
tested at its specified power input level and duty cycle and
should require a minimum of maintenance through years of
operation. Additionally, each
LK 400.500 series
Amplifier
will operate many MARS frequencies without modification (see
MARS expanded coverage chart). A quiet, efficient cooling
system maintains the RF deck and
Power Supply chamber
temperature ensuring long service life. All
LK 500 series
linear amplifiers feature the new ALO (Automatic Lock Out)
circuit which senses unacceptable plate/grid currents and
voltages or improper
Amplifier tuning and stops
Amplifier
operation.
Tuning the
Amplifier is a simple procedure, since each unit
is designed for long term stability in virtually any
operating situation. Tuned input and standard relay
switching circuitry makes the
LK 400.500 series compatible
with any available solid state or tube
Transceiver or
transmitter. Despite their straight-forward design and
minimal user required adjustment, the
LK 400.500 series
linear amplifiers are sophisticated electronic instruments.
Therefore, if the unit is operated outside the parameters
outlined in this owner’s manual, damage may result. Please
read this manual carefully before putting your new Amp
Supply
LK 400.500 series linear
Amplifier on the air.
