Note on Schematic Diagrams:
• All capacitors are in
µ
F unless otherwise noted. (p: pF)
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.
•
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 M
Ω
).
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

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.
