Fig. 4. Voltage and Resistance Analysis Chart

1. Resistance readings at these points will vary since they are in series with the leakage res is tance of the electrolytic condensers which is subject to change.
2. All D.C. measurements were made with a meter having a sensitivity of 20,000 ohms per volt. A.C. measurements were made with a 1000 ohms per voltmeter.
3. Measured values are from socket pin to circuit ground: (pin 8 of 12SQ7 socket).
4. Tolerances of component values make possible a variation of +/- 20% in readings indicated in chart.
5. Socket connections are shown as bottom views.

ALIGNMENT INSTRUCTIONS
Punch marks are provided on the dial back plate at 600 kc, 1000 kc, 1400 Kc and 1600 Kc for alignment purposes. With tuning condenser completely open, set dial pointer to 1600 Kc punch mark. Connect output meter across voice coil terminal. on speaker frame. Connect low side of signal generator lead thru a 0.1 mfd coupling.condenser to chassis ground. Connect high side of generator thru proper dummy antenna to the receiver external antenna connection. Keep signal generator output at lowest practical level and proceed according to table below.
