THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is printed in each block.)
• A : B+ Line.
• B : B– Line.
• 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).
Voltage variations may be noted due to normal production
tolerances.
• Waveforms are taken with a oscilloscope.
