SCHEMATIC DIAGRAMS
BEFORE SERVICING THIS CHASSIS, READ THE WARNINGS AND CAUTIONS
IN THE PREFACE.
WARNING
The international hazard symbols in the schematic diagram and the parts list des-
ignate components which have special characteristics important for safety and
should be replaced only with types identical to those in the original circuit or specified
in the parts list. The mounting position of replacements is to be identical with origi-
nals. Before replacing any of these components, read carefully the PRODUCT
CAUTIONSAFETY NOTICE. Do not degrade the safety of the receiver through improper ser-
vicing.
NOTES:
1. RESISTOR
Resistance is shown in ohm [K = 1.000, M = 1.000.000]. All resistors are 1/6W and 5% tolerance car-
bon resistor, unless otherwise noted as the following marks.
1/2R = Metal or Metal oxide of 1/2 watt
1RF = Fuse resistor of 1 watt
1/2S = Carbon composition of 1/2 watt
10W = Cement of 10 watt
K = ?10%
G = ?2%
F = ?1%
2. CAPACITOR
Unless otherwise noted in schematic, all capacitor values less than 1 are expressed in ?F, and the val-
ues more than 1 in pF.
All capacitors are ceramic 50V, unless otherwise noted as the following marks.
+
Electolytic capacitor
M
Mylar capacitor
3. The parts indicated with have special characteristics, and should be replaced with identical parts
only.
4. Voltages read with DIGITAL MULTI-METER from point indicated to chassis ground, using a color bar
signal with all controls at normal, line voltage 120 volts.
5. Waveforms are taken receiving color bar signal with enough sensitivity.
6. Voltage reading shown are nominal values and may vary ?20% except H.V.
