Notes
VOLTAGE & WAVEFORM NOTATIONS - Voltage readings and
waveform
measurements were taken
with
a color video signal injected at the video
input
terminal. Figures in ( ) represent voltage readings
taken while receiving a black and
white
sign. Each variable resistor
was
set
to
condition
at
time
of
shipment.
After
adjustments have been made, the figures
will
vary
and
the
figures should be used
for
reference only.
VOLTAGE READINGS
Multimeter
set
at
20KO/volt DC.
All values given are
DC
voltages.
REFERENCE
WAVEFORMS - Scope sweep speed
set
at:
Hor -
20
/tS/div
Vert
-
5V/div;
Unless other speed is specified.
SCHEMATIC NOTES - Unless specified otherwise:
Resistors:
Capacitors:
Inductors:
All values
are
in
ohms,
1/4
watt
carbon
Values
of
1 or higher are pF.
Values less than 1 are /tF,
50V,
ceramic
Electrolytic values are in /tF,
NP
indicates non-polar (bipolar)
Values are in
uH
<;;>
indicates a
test
point
connection
;m
indicates chassis ground
Hz
indicates cycles per second
SAFETY - For safety, maximum reliability, and continued good performance, use specified replace-
ment
parts. All safety items have been identified
with
the
symbol
*.
FR
is
an
abbreviation
for
FUSI-
BLE
RESISTOR~.
FR's act like fuses and are used
as
safety
items.
They
are
to
be replaced
with
specified parts.
NOTICE - This circuit diagram and the circuit constants are subject
to
change for improvement
without
notice.
