4、c Voltmeter.-The electronic voltmeter in the Chanalyst or VoltOhmyst provides an unexcelled output indicator. It should be con- nected to the AVC bus. Test-Oscillator.-Connect the low side of the test -oscillator to the receiver chassis through a .01 mfd. capacitor. When the electronic voltmeter is

With the output meter alignment method the oscillator output should be kept as low as possible. Calibration Scale.-The glass tuning dial may be easily removed from the cabinet and tem
