SERVICING IN THE FIELD
SAFETY GLASS REMOVAL
Remove 2 screws at bottom of picture tube holding trim.Remove spring holding trim strip around picture tube. Re-move 2 screws holding metal shell strap. Remove strap andfront glass.
FUSE
A fuse wire is used for filament protection. (For location,see M4 in photo "Chassis Top View".)
FUSE DEVICE
A 5.6fi fusible resistor is used for low voltage power sup-ply protection. (For location, see "Tube Placement Chart'.')
TUNER OSCILLATOR ADJUSTMENTS
To touch-up the VHF Oscillator, remove Channel Selectorand Fine Tuning knobs.
AGC
The AGC may be varied by means of a Range Switch. (For
location, see "Tube Placement Chart".)
FOCUS
The focus may be varied by connecting the lead from pin 4of the picture tube to various voltage points. (For location,see photo "Chassis-Top View".)
HORIZONTAL OSCILLATOR FIELD ADJUSTMENTS
Coarse adjustment of the Horizontal Hold is accomplishedby the proper setting of the Horizontal Frequency control.(For location, see "Tube Placement Chart".)
WIDTH
The width may be varied by adjusting a metallic sleeve, lo-cated between the yoke and the picture tube neck, in or outof the yoke.
CENTERING
Centering is accomplished by 2 magnetic rings, located be-hind the yoke, on the neck of the picture tube.

TUNER ALIGNMENT INSTRUCTIONSPRE-ALIGNMENT INSTRUCTIONS FOR TUNER T100, T101
The high voltage lead should be securely taped and kept away from the chassis.Allow a 20 minute warm-up period for the receiver and test equipment.Suggested alignment tools: A201, A202, A203, A206, A207, A208, A221 . . .General Cement #5009, 8195, 8274, 8275, 8728, 8987

VHF RF AND MIXER ALIGNMENT
Set Range switch to "Normal".Connect the negative lead of a 1. 5 volt bias supply to point <^> . Positive to chassis.Detune the Mixer Plate coil by connecting a 10 to 20mmf capacitor across it.Connect the synchronized sweep voltage from the sweep generator to the horizontal input of the oscilloscope for horizontal deflection.The sweep generator output lead should be terminated with its characteristic impedance, usually 50 ohms.Use only enough sweep generator output to provide a usable pattern on scope.Use 10MC sweep unless otherwise noted.Coils not containing adjustable cores are adjusted by expanding or compressing coil turns.
