Fadalette: A tabulation of voltages in this set on D.C. The D.C. and A.C. readings are for a 110 V. line. Bias readings
are taken across re-spective bias resistors. The D.C. input is 34 W., and the A.C., S6 W.
Stewart-Warner Companion Chassis Series 108 and 108-X, Models 10 to 20. With the volume control tuned full on, the following
approximate voltages should be read to the frame of unit C (using a high resistance voltmeter).
All sets of the "universal current" type now on the market require that the Service Man check the position of the power
plug in its socket to determine whether it is correctly poled. It is seldom that the chassis frame connects directly to
the power line. Circuit oscillation at the high-sensitivity setting of the volume control is normal in many models. The
results obtained with ultra-midget sets will greatly depend upon local reception conditions.
