Models 118/201 Inoperative at 12 MC.
This
condition is caused by mis-alignment of the RF circuit with respect to the
oscillator circuit. It can be corrected by setting the dial to 12 megacycles
and adjusting the setting of the oscillator high-frequency compensating
condenser, No. 22 [on Model 118, Philco Service Bulletin
No. 194, No. 21 for the Model 201] slightly until the noise
level comes up to normal. Now tune a station at 11.8 megacycles and further
adjust the compensating condenser, re-tuning the dial slightly as this is
being done until maximum volume is reached.
From the Philco Serviceman - February, 1935.
