THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is printed in each block.)
For Printed Wiring Boards.
Note:
• X : Parts extracted from the component side.
• Y : Parts extracted from the conductor side.
• : Internal component.
f
• : Pattern from the side which enables seeing.
(The other layers' patterns are not indicated.)
Caution:
Pattern face side: Parts on the pattern face side seen
(Conductor Side) from the pattern face are indicated.
Parts face side: Parts on the parts face side seen from
(Component Side) the parts face are indicated.
Caution:
Pattern face side: Parts on the pattern face side seen
(SIDE B) from the pattern face are indicated.
Parts face side: Parts on the parts face side seen from
(SIDE A) the parts face are indicated.
• AMP and MB-1509 boards are multi-layer printed board.
However, the patterns of intermediate layers have not
been included in diagrams.
• Indication of transistor.

Note 1: Among mounted electrical parts on each boards, only
parts that are described in the electrical parts list can
be replaced for repair.
The parts that are not described in the electrical parts
list cannot be replaced with single for repairing.
Note 2: When the complete AMP board is replaced, refer to
"SPREADING OF COMPOUND" on page 8.
• Suffi x-11/Suffi x-12 discrimination of AMP board
The AMP board has been changed in the midway of pro-
duction.
Distinguishing by the part No. on the AMP board.

For Schematic Diagrams.
Note:
• 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 1/4 W or less unless otherwise
specifi ed.
• 2 : Nonfl ammable resistor.
• 5 : Fusible resistor.
• C : Panel designation.
Note: The components identifi ed by mark 0 or
dotted line with mark 0 are critical for safety.
Replace only with part number specifi ed.
Note: Les composants identifi és par une marque
0 sont critiques pour la sécurité.
Ne les remplacer que par une piéce portant
le numéro spécifi é.
• A : B+ Line.
• Voltages and waveforms are dc with respect to ground
under no-signal (detuned) conditions.
no mark : POWER ON
* : Impossible to measure
• Voltages are taken with VOM (Input impedance 10 M).
Voltage variations may be noted due to normal production
tolerances.
• Waveforms are taken with a oscilloscope.
