f
: internal tolerance.
• C : panel designation.
• A : B+ Line.
• Power voltage is dc 6.0V and fed with regulated dc power
supply from battery terminal.
• 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.

set requires a special tool.
• The voltage and waveform of CSP (chip size package)
cannot be measured, because its lead layout is different
from that of conventional IC.
