SAFETY GLASS REMOVAL
Follow steps 1 thru 4 of "Disassembly Instructions",
Remove 4 screws holding upper and lower retainers onop-
tical unit.Removebeam splitter for cleaning.
FUSE
One fuse is used forlow voltagepower supply protection.
(Forlocation, see "Transistor & TubePlacement Chart".)
TUNER OSCILLATOR ADJUSTMENTS
To touch-up theVHF Oscillator, remove Channel Selector
and FineTuningknobs.
AGC
The AGCmaybe varied by means ofa Rangeswitch. (For
location, see " Transistor & TubePlacement Chart".)
FOCUS
The focus maybe varied by connecting the leadfrom pin4
of the picture tube to variousvoltagepoints.(Forlocation,
see photo "Cabinet-Rear View".)
HORIZONTAL OSCILLATORFIELD ADJUSTMENTS
Coarseadjustment ofthe HorizontalHold is accomplished
by the proper setting ofthe AuxiliaryHorizontalHold. (For
location, see "Transistor & TubePlacement Chart".)
BUZZ ADJUSTMENT
To eliminate intercarrier buzz,adjust the Discriminator
secondary (A12) located ontopof chassis.
CENTERING
Centering is accomplished by2 magnetic rings andbythe
beamaligningmagnet,locatedbehindyoke onthe neck of

VIDEO IF ALIGNMENT
Connect the synchronizedsweepvoltagefrom the sweep generator tothe horizontalinput ofthe oscilloscope for horizontal deflection.
The generator output leadshould be terminated with its characteristic impedance, usually 50 ohms.
Use only enough sweep generator output to provide a usablepattern on scope.
Connect a variable bias supply betweenTP-3 and chassis. The required bias will range from -1.5 to+3 volts. Duringalignment set
