INTNCITXrcTION
The
Amp
Supply
LK500ZB
Linear
Amplifier is a
compact
2500
Watts
PEP
160-15
meter
amplifier of
modern
design. It is
a
high
performance
pieee
of
equipment
requiring
a
minimum
of
maintenanee
through years of
operat
ion.
The
LK500ZB
was
engineered
conservatively, with
Ameriean components
and
ingenuity.
The
unit is field-tested
and rated for
2500
Watts
PEP
input
continuous
in
SSB
service
and
2000
Watts
DC
input
along
with
many
MARS
operating frequencies, without modifications.
T\ro EIMAC
3-5002
tr
iodes
are
employed,
operating
in
grounded
grid in
conjunction
with
a
solid state
power
suppty eapable of
either
11?V
or
234V
operation.
The
LKS00ZB
uses a double duty
cool
ing
system
which
al
lows cool
ing
of
not
only
the tubes,
but
the
power
supply
as
wel
l.
Tuning
the
LKs00ZB
is a
simple procedure, since
the
unit
is
designed
for
long-term
stabil ity in virtual ly
any operating
situation.
Tuned
input
and
standard
relay
switehing
circuitry
makes
the
LKS00ZB
compatible
with any solid state or
tube
transeeiver
or
transmitter
available.
The LKs00ZB,
despite
its
straight-forward
des
ign
and
minimal user
required adjustment,
is
nonetheless
a
sophistieated
electronic instrument.
Therefore,
if
the unit is
operated
outside the
parameters
outl ined in this
ownerts
manual,
it is
possible
that
damage
ean resul
t.
Please read
this
mqnual
careful
ly before
putt
ing
your
LK500ZB
on
the
air.
XANNING
TO
TAKE
FULL
ADVANTAGE
OF
THE LK500ZB COOLING SYSTEM,
IT
IS
REQUIRED THAT THE
AMPLIFIER BE
OPERATED
WITH
AT
LEAST Z-LI2N
CLEARANCE
ON
BOTH
SIDES AND
TOP
OF THE UNIT.
CAUTIONS
1.
Make
no attempt
to put
the
LK500ZB
in
service outside
of
the
cabinet.
Contact
witn
high voltages
in this Amplifier
can
be
FATAL TO THE
HUMA}.I
BODY.
Never
attempt
to
operate the
LKs00ZB
with drive
power of
more
than
125 Watts!
Never attempt to operate the
LK500ZB
without first
eonnecting
it to
an
antenna
with
an
SWR
of less
than
2zl,
or
a
50
Ohm dunnny
load
of suffieient
power
handling eapaeity
or
ser
ious
damage
may
resul
t to
the
ampl i
f
ier.
