f
: internal component
: B+ Line.
• Power voltage is dc 1.5 V and fed with regulated dc power supply
from battery terminal.
• Voltages and waveforms are dc with respect to ground under no-
signal (detuned) conditions.
no mark : PLAY
• Voltages are taken with a VOM (Input impedance 10 M
).
Voltage variations may be noted due to normal production toler-
ances.
• Waveforms are taken with a oscilloscope.
