Description: Linear Amplifier
Information:
                                    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 longterm
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.
