To set pointer, completely mesh tuning capacitor and align pointer with last reference mark at low frequency end of dial, Volume control should be in maximum clockwise position. Bass and treble controls should be in maximum counter-clock wise position. Output of signal generator should be no higher than necessary to obtain an output reading. Low side of signal generator and indicating meter should be connected directly to chassis at all times. Use an insulated screw driver with 1/16" thick blade for adjusting IF transformers.
STAGE GAIN MEASUREMENTS
Dial Cord Drive
Top reading in AM position, bottom italic reading in FM
DC Voltages measured with vacuum-tube voltmeter
AC Voltages measured at 1,000 ohms per volt.
Socket connections are shown as bottom views.
Measured values are from socket pin to common negative.
Line voltage maintained at 117 volts for voltage readings.
Nominal tolerance on component values makes possible a variation of plus/minus 10 % in voltage.
Voltage measurements are with no signal applied.
