Where readings may vary according to the setting of the service controls, both minimum and maximum readings are given. RadioFans.CN ALIGNMENT INSTRUCTIONS ALIfiNMENT INSTRUCTIONS-READ CAREFULLY BEFORE ATTEMPTING ALIGNMENT This receiver uses a brute rorce type high voltage power supply and extreme caution should be exercised when working beneath the chassis. VIDEO IF ALIGNMENT The signal may be Injected Into the video IF channel by means of several turns of hookup wire wrapped a round the 12AT7 mixer tube (V2).

Adjust for zero reading. A positive and negative reading will be obtained on either side of the correct setting. After recei- ver has been fully aligned tune In a TV station sound carrier and adjust A7 for minimum hum, if necessary. ANTENNA ; ; ; OSCILLATOR ALIGNMENT When adjusting the oscillator settings, it must be borne in mind to set the oscillator circuits to the same channels as the antenna and RF amplifier circuits were aligned. The oscillator operates 33MC above the sound carrier on the low band channels and 33MC below the sound carrier on the high band channels.
