Output Meter Alignment.-If this method is used, connect the meter across the voice coil, and turn the receiver volume control to maximum. Teat-Oscillator.-For all alignment operations, connect the low

5、 side of the test -oscillator to the receiver chassis, and keep the output as low as possible to avoid a -v -c action. Electronic Voltmeter.-The electronic voltmeter in the Chanalyst or VoltOhmyst provides an unexcelled output indicator. It should be connected to the AVC bus, and the test -oscillato

6、r output adjusted to produce several volts of AVC. Calibration Scale.-The glass tuning dial may be easily removed from the cabinet and temporarily attached to the chassis for quick reference during alignment. In the event that only the chassis is returned for service, and the cabinet with its tuning

7、 dial is left in the customers home, the calibration scale printed in this service note can be used in conjunction with an ordinary 12 -inch ruler as an accurate and convenient substitute for the regular dial. Each method is described below. Using Tuning Dial. - 1. Slide out the flat spring clamp at

8、 each end of the dial, and remove the glass dial from the cabinet. 2. With gang in full mesh, move the dial pointer to the reference mark at the left-hand end of the dial backing plate. 3. Place the glass dial under the pointer so that the extreme left scale graduations coincide with the pointer. Us

9、e scotch tape to hold the glass dial in this position. 4. After completion of alignment, replace the glass dial in cabinet, taking care that the fibre light shields are in correct position at ends of dial. Phonograph Motor Service Data:- The phonograph motor is of the self starting synchronous type

10、and operates the turntable through friction drive between the motor drive spindle and the rubber tired idler on the rim of the turntable. The motor should be lubricated once or twice a year by placing a few drops of S. A. E. 20 (or equivalent) on the turntable spindle and saturating the oil retainin

11、g felt pads on the motor shaft with S. A. E. 10 oil. Caution-The motor drive spindle and the rubber tire on the idler must be kept clean and entirely free from oil and grease at all times.

24、TH GANG AT MAX. CAPACITY 6. Proceed in the same manner to adjust for the remaining - four stations. On the 880 to 1,550 kc push-button, the higher frequency stations may be received with L24 either in or out (oscillator frequency 3TtJRNS 455 kc below or 455 kc above the station frequency). The adjus

25、tment with this core in its out position (oscillator frequency V I72 453 kc above the station frequency) is the correct one. NOTE: Clockwise adjustment of cores and trimmers tunes the cir- cuits to lower frequencies. Replacement Parts Insist on genuine factory -tested parts, which are readily identi
