Connec- tions for the oscilloscope are shown in the chassis drawing. Output Meter Alignment.-If this method is use

11、d, connect the meter across the voice coil, and turn the receiver volume control to maximum. Test-Oscillator.-For all alignment operations, connect the low side of the test -oscillator to the receiver ground terminal (G), and keep the output as low as possible to avoid a -v -c action. Calibration Sc

12、ale on Indicator -Drive -Cord Drum.-The tuning dial is fastened in the cabinet and cannot be used for reference during alignment; therefore, a calibration scale is attached to the rear of the drum which is mounted on the front shaft of the gang condenser. The setting of the gang condenser is read on

13、 this scale, which is calibrated in degrees. The correct setting of the gang in degrees, for each align- ment frequency, is given in the alignment table. As the first step in r -f alignment, check the position of the drum. The 180 mark on the drum scale must be vertical, and directly over the center

14、 of the gang -condenser shaft when the plates are fully meshed. The distance from the front of the chassis to the drum must not exceed 3/8 -inch. The drum is held to the shaft by means of two set screws, which must be tightened securely when the drum is in the correct position. Pointer for Calibrati
