SERVICING IN THE FIELDTUNER OSCILLATOR ADJUSTMENTS

Touch-up adjustment of the VHF Oscillator is possible byremoving the Channel Selector and Fine Tuning knobs. Setthe Fine Tuning at the center of its range. The adjustments(located in a circle around the shaft) should be made in se-quence from the highest to the lowest channel in the area.Channel 13 adjustment is located at 9 o'clock, proceed in acounterclockwise direction adjusting for best picture andsound.

SAFETY GLASS CLEANING

Use only mild soap and water to clean safety glass.

AGC

The AGC may be varied by a Local-Distance switch. (Forlocation, see tube placement chart.)

FOCUS

HIDDEN ADJUSTMENTS

The Vertical Linearity Adjustment is located under Bright-ness knob, the Height under Vertical Hold and HorizontalRange under Horizontal Hold.

HORIZONTAL LINEARITY

The focus maybe varied in steps by the position of a plug inthe Focus Adjustment board.

WIDTH

The width may be varied by Width control. (For location,see tube placement chart.)

The Horizontal Linearity can beadjustedby means of amag-net located to the left of the yoke.

HORIZONTAL OSCILLATOR ADJUSTMENTS

Set the Horizontal Hold at the center of its range and removethe knob. Adjust the Horizontal Range (inner shaft) until thepicture synchronizes horizontally.

SOUND IF DETECTOR BUZZ ADJUSTMENT

To eliminate intercarrier buzz, adjust the Buzz control forMINIMUMbuzz and maximum sound. (For location, see tubeplacement chart.)

FUSE DEVICE

A 5. 6SJ fusible resistor (R78) is used for low voltage powersupply protection. (For location, see tube placement chart.)

CENTERING

Centering is accomplished mechanically by adjustment ofVertical and Horizontal Centering Magnets.

VHF OSCILLATOR ALIGNMENT

The signal generator output lead should be terminated with Its characteristic Impedance, usually 50 ohms.Set the Fine Tuning to the center of Its range.Use only enough signal generator output to provide a usable Indication on scope.This procedure uses the traps of the Video IF strip. They must be In proper alignment before attempting to align the oscillator.
