Calibration Scale on Indicator-Drive-Cord-Drum.-The tuning dial is fastened in the cabinet and cannot lie used for reference during alignment; therefore, a calibration scale is attached to the tuning drum. The setting of the gang

12、 condenser is read on this scale, which is calibrated in degrees. The correct setting of the gang in degrees, for each. alignment frequency, is given in the alignment table. As the first step in r -f alignment, check the position of the drum. The 1 Mo mark on the drum scale must be vertical and dire

13、ctly under the center of the shaft of the tuning drum when the plates are fully meshed. 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. On the inner side of the tuning drum are Iseo projections which serve as stops

14、 to prevent extreme rotation of the gang condenser. The tuning drum should be set so that the stop limiting clockwise move- ment of the drum takes effect just as the gang condenser plates are becoming fully meshed, thus preventing stress on the gang (lue to extreme rotation. Pointer for Calibration

15、Scale,-Improvise a pointer for the calibra- tion scale by fastening a piece of wire to the chassis, and bend the wire su that it points to the n mark on the calibration scale when the plates are fully meshed- RECT w C5-AtYT- 20 MC. r1.-C11-A11T 6MC. hlt C3-ArIT-1500KC. 7 fC6-OSC- 20 MC. 4 15T.
