: B+ Line.
• Voltages and waveforms are dc with respect to ground
under no-signal (detuned) conditions.
no mark : TUNER (FM)
*
: 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.
Voltage variations may be noted due to normal production
