(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.
• W : Indicates side identi fi ed with part number.
•
f

• A : B+ Line.
• Power voltages is dc 14.4V and fed with regulated dc
power supply from ACC and BATT cords.
• Voltages and waveforms are dc with respect to ground
under no-signal (detuned) conditions.
no mark : TUNER
• 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.
