Voltage Test

If all connections are found to be correct, the tubes may be Inserted and the line-cord plug connected to a 110-volt, «0 cycle receptacle, and the speaker (1600 to 2000 ohm field) plugged in. A slight turn of the tone control knob to the right will turn on the receiver. After a brief warm-up period the voltages shown on the Schematic Diagram should be checked with a high-resistance voltmeter, If available. Voltages indicated are measured from the point shown, to the chassis, with the chassis as the negative terminal. If values measured are materially different than shown on the diagram, a thorough recheck of the circuit should be made. Be sure the receiver is turned off and the line-cord dis-connected from the power receptacle while the wiring is being: checked.
