Note on Schematic Diagram:
• All capacitors are in µF unless otherwise noted. pF: µµF
50 WV or less are not indicated except for electrolytics
and tantalums.
• All resistors are in Ω and 1/4 W or less unless otherwise
specified.
•
%
: indicates tolerance.
• C : panel designation.
• U : B+ Line.
• Power voltage is dc 1.5 V and fed with regulated dc power
supply from battery terminal.
• Voltages and waveforms are dc with respect to ground
under no-signal (detuned) conditions.
• Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal production tolerances.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal production tolerances.
• Circled numbers refer to waveforms.
• Signal path.

SECTION 4
EXPLODED VIEWS
NOTE:
• -XX, -X mean standardized parts, so they may
have some differences from the original one.
• Items marked “*” are not stocked since they
are seldom required for routine service. Some
delay should be anticipated when ordering these
items.

NOTE:
• Due to standardization, replacements in the
parts list may be different from the parts
specified in the diagrams or the components
used on the set.
• -XX, -X mean standardized parts, so they
may have some difference from the original
one.
• Items marked “*” are not stocked since they
are seldom required for routine service.
