If not adjust A6 until they are equal. Move VTVM to pin 1 of V13. The VTVM should read zero. If not, adjust A7 until should swing positively and negatively on either side of this setting. VTVM does read zero.

IFIG. 2 PAGE 6 RadioFans.CN ALIGNMENT INSTRUCTIONS CCONTJ OSCILLATOR ALIGNMENT The RF circuits of the Dumont Input tuner are very stable and will normally not require alignment In the field. The RF Amplifier circuits of the Sarkes Tarzlan tuner are also very stable and should not require adjustment. However, It may be necessary to adjust the oscillator circuits In those models uslns the Tarzlan tuner. To adjust the oscillator circuits for this tuner follow the Instructions and chart below: (a). Replace the oscillator tube If removed for proceeding steps, (b). Do not attempt oscillator alignment unless sound IF channel has been accurately aligned. DUMMY ANTENNA Two 125S carbon res.
