ALIGNMENT INSTRUCTIONSALIGNMENT INSTRUCTIONS— READ CAREFULLY BEFORE ATTEMPTING ALIGNMENT
The high voltage shock hazard may be eliminated by removing the horizontal oscillator tube, (V17), from its socket. •
VIDEO IF ALIGNMENT
Remove the converter tube, (V2), from its socket and replace it with a 6J6 which has Pin 1 removed. This will disable the local oscillator andprevent the possibility of erroneous indications.
Connect the negative lead of a 3 volt battery to the junction of R45 and C5. Connect the positive lead to chassis.

RF TUNER ALIGNMENT
Remove the dummy converter tube and replace the original 6J6 in its socket.Connect the negative lead of a 3. 5 volt supply from a battery to terminal 3 of the HF unit terminal board, connect the positive lead to chassis.Disconnect the link between L18 and L19. Connect a 39S2 carbon resistor across terminal 1 and 2 on the terminal board, and loosely couple the link wire
to terminal 2.Detune A10 fully clockwise, (all the way out).Detune A27 fully counter clockwise, ( in later production L16 is fixed and cannot be tuned).Set the fine tuning control to the mid-position of its range.

Adjust for zero reading as in step 17. Thenover shoot the adjustment as in step 19. Ad-just A15 to reset the oscillator to properfrequency.
Check all high band channels for proper re-sponse with markers above 80%. If markersdo not appear within 80% repeat step 13. IfA19 is adjusted the adjustment should be over-shot a small amount and compensated for byadjusting A25 for maximum amplitude betweenthe markers. If the valley in the top of thecurves on the high channels seems excessive,adjust A27 to flatten the curve. In later pro-ductions A27 may be fixed and not required ad-justment.
Check the oscillator frequency for the high band channels. If the oscillator is off frequency, over shoot the adjustment of A15 and compensate for itby adjusting A26 for zero voltage at Point C .

Check all low band channels for responsesimilar to figure 4 and the injection voltage atPoint D which should be - 3 volts. Also checkchannels 7 thru 13.
If necessary adjust A15 for zero voltage as instep 17.
Adjust for zero reading. A positive and neg-ative reading will be obtained on either side ofthe correct setting.
Turn channel switch to channel 8 and adjust A24 for proper response . When A24 is properly adjusted the response curve will be slightly wider with aslightly deeper valley in the center. Check all channels for: (1) proper response, (2) oscillator injection voltage at point D , and (3) oscillator frequency.Make slight touch up adjustments, if necessary. If A16 and A24 are changed considerably repeat step 28.
Disconnect the 39S2 resistor from terminals 1&2 on terminal strip and reconnect the link. Repeat steps 8 and 9 of VIDEO IF ALIGNMENT.

AGC SWITCH SETTING
In strong signal areas the normal setting of the AGC switch is counter-clockwise. If interference of the impulse type is encountered turn theswitch to the center position.In very weak signal areas, turn the switch to the clockwise position.
FM TRAP ADJUSTMENT
If interference from a strong FM station is encountered, adjust A38 to eliminate or minimize the interference. Otherwise A38 requires noadjustment.
