Models 118/201 Problems 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.
