WARNING
: BEFORE SERVICING THIS CHASSIS, READ THE “SAFETY PRECAUTION” AND “PRODUCT SAFETY
NOTICE” INSTRUCTIONS ON PAGES 3 AND 4 OF THIS MANUAL.
CAUTION
: The international hazard symbols "
" in the schematic diagram and the parts list designate 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 originals.
Before replacing any of these components, read carefully the SAFETY PRECAUTION and PRODUCT SAFETY NO-
TICE instructions on pages 3 and 4 of this manual. Do not degrade the safety of the receiver through improper servicing.
NOTE:
1. RESISTOR
Resistance is shown in ohm [K = 1,000, M = 1,000,000]. All resistors are 1/6W and 5% tolerance
carbon resistor, unless otherwise noted as the following marks.
1/2R = Metal or Metal oxide of 1/2 watt
1/2S = Carbon compsistion of 1/2 watt
1RF = Fuse resistor of 1 watt
10W = Cement of 10 watt

2. CAPACITOR
Unless otherwise noted in schematic, all capacitor values less than 1 are expressed in
µ
F, and
the values more than 1 in pF.
All capacitors are ceramic 50V, unless otherwise noted as the following marks.
Electolytic capacitor
Mylar capacitor
3. The parts indicated with "
