Note on Schematic Diagrams:
• All capacitors are in µF unless otherwise noted. (p: pF)
50 WV or less are not indicated except for electrolytics and
tantalums.
• All resistors are in Ω and

W or less unless otherwise
specified.
• C : panel designation.
• A : B+ Line.
•Voltages and waveforms are dc with respect to ground
under no-signal (detuned) conditions.
∗ : Impossible to measure
•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.
F : AUDIO
•Abbreviation
CND : Canadian model
MX : Mexican model
TW : Taiwan model
Note on Printed Wiring Boards:
• X : parts extracted from the component side.
• Y : parts extracted from the conductor side.
• : Pattern from the side which enables seeing.
(The other layers' patterns are not indicated.)
• DIAT AMP board is multi-layer printed board.
However, the patterns of intermediate layers have not been
included in diagrams.
• Indication of transistor.

Note:
The components identi-
fied by mark 0 or dot-
ted line with mark 0 are
critical for safety.
Replace only with part
number specified.
Note:
Les composants identifiés
