During the alignment of this receiver, the pointer will have to be set to a specific frequency. Since the diol

5、scale is an integral part of the cabinet, the receiver chassis must be in the cabinet for correct posi tioning of the gang condenser and pointer. Before setting the pointer to the desired frequency, it will be necessary to check the position of pointer with respect to the gang condenser. To accompli

6、sh this, rotate tuning knob fully counter-clockwise until gang condenser is fully meshed. With gang in this position, pointer should be parallel with base of cabinet. If the pointer is not properly positioned, hold the Tuning Knob steady and move the pointer manually to the proper place. 2. Before r

Then turn the tuning shaft until pointer is set to desired frequency for alignment ond taking care not t

Connect an output meter across the speaker voice coil or from the plate of the 35C5 tube to B (see voltage chart for convenient connec tion point) through a 0.1 Mfd. condenser. 4. Connect ground lead of signal generator to B lug. CAUTION: If your signal gene

9、rator is designed with an AC-DC power supply, connect ground lead to B lug through a .25 Mfd. condenser. (See voltage chart for convenient B connection.) 5. Set tone control to its maximum clockwise position. 6. Set volume control at maximum volume position and use a weak signal from the signal gene

After alignment has been completed ond chassis reassembled in cabinet and pointer properly positioned, check calibration over entire dial and should the calibration error be objectionable, repeat procedure, exer cising greater precaution in the initial setting of the pointer.
