• 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
