15、 RadioFans.CN PAGE 552-C T-63 Alignment Procedure Cathode -Ray Alignment is the preferable method. Connections for the oscillograph are shown in the schematic drawing. Output Meter Alignment.-If this method is used, connect the meter across the voice coil, and turn the receiver volume control to max

16、imum. Teat-Oscillator.-For all alignment operations, keep the output as low as possible to avoid a -v -c action. The low side of the test - oscillator should be connected to the receiver chassis. Calibration Scale on Indicator -Drive -Cord Drum.-The tuning dial is fastened in the cabinet and cannot

17、be used for reference during alignment; therefore, a calibration scale is attached to the tuning drum. The setting of the gang 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.

18、Pointer for Calibration Scale.-Improvise a pointer for the calibration scale by fastening a piece of wire to the chassis, and bend the wire so that it points to the 0 mark on the calibration scale when the plates are fully meshed. Dial -Indicator Adjustment.-After fastening the chassis in the cabine

19、t, adjust the dial indicator along the drive cable to the 540 kc mark, gang condenser fully meshed. The indicator has a clip for attachment to the cable. Precautionary Lead Dress: (1) Dress C8 (Oscillator coil to range switch) and its leads away from surrounding wires and chassis. (2) Dress R2 (Scre

20、en to B+) away from surrounding wires and parts. (3) Dress power switch leads away from 6SQ7 and 6F6G tube sockets. For additional details, refer to booklet RCA Victor Receiver Alignment.
