B. Power Supply Adjustment (Assy. 7H046)

1. Connect radio to a suitable 120 VAC source. Be sure that the D.C. power cable is not pluged in also.

2. Apply power to the unit with front panel OFF-ON switch. The lights behind the meters should be lit.

3. Connect a voltmeter between C-8 11 (+) end and the chassis. Adjust 8835 for a reading of 13.6 volts (± .1).

4. Connect a voltmeter between C809 (+) end and the chassis. Adjust 8808 for a reading of 10.0 volts (± .1).

5. Connect a voltmeter between C806 (+) end and the chassis. A reading of 5 volts (± .3) should be noted. No adjustment is possible in this circuit.

6. Ripple on the three supplies should be less than l0mv p-p. Measure across C811, C809, and C806 for corresponding +13.6, +10, and +5 volt supplies.

7. To check DC operation, remove the AC power source and connect the radio to a 5 amp or greater source of 13.6 volts (± .5v) with the DC cable provided. Measure the voltage in steps 4 and 5 above. They should be the same as noted on AC. Step 3 voltage will be equal to input supply voltage.
