• REMOVAL OF ANODE-CAP
Note:
• After removing the anode, short circuit the anode of the picture tube and the anode cap to the metal chassis, CRT
shield or carbon paint on the CRT.
• REMOVING PROCEDURES
Turn up one side of the rubber cap in the direction
indicated by the arrow 
a.
Using a thumb pull up the rubber cap firmly in the direc-
tion indicated by the arrow 
b.
When one side of the rubber cap is separated from the
anode button,  the anode-cap can be removed by
turning up the rubber cap and pulling it up in the
direction of the arrow 
c.
• HOW TO HANDLE AN ANODE-CAP
Do not damage the surface of anode-caps with
sharp shaped objects.
Do not press the rubber too hard so as not to
damage the inside of anode-cap.
A metal fitting called the shatter-hook terminal is
built into the rubber.
Do not turn the foot of rubber over too hard.
The shatter-hook terminal will stick out or damage
the rubber.

2. Position neck assy as shown in Fig 2-1.
3. Set the pattern generator raster signal to a green
raster.
4. Move the deflection yoke to the rear and adjust with
purity control so that the green is at the center and the
blue and the red take up equally sized areas on each
side. (Figures 2-2 through 2-4.)
5. Move the deflection yoke forward and adjust so that the
entire screen is green. (Figure 2-2.)
6. Switch the raster signal to blue, then to red and verify
the condition.
7. When the position of the deflection yoke have been
decided, fasten the deflection yoke with the screws and
DY spacers.
8. If the beam does not land correctly in all the corners,
use a magnet to adjust it.
