8K Series ProPalette Repair Manual

Disassembly of the CRT

1. Slightly twist and remove the round mu metal shield from the tube. (This
shield has a ground cable and tie wrap attached, which should be left in place.)
Some hot melt adhesive will be left in the shield. Remove the hot melt inside
the shield. (Figure 5-26)
2. Loosen the metal clamp that holds the yoke in position on the CRT. (The yoke
is also held with hot melt adhesive.)
3. Firmly twist the yoke to break the hot melt and remove the yoke from the
tube. Remove the hot melt from the inside yoke surface.
4. Remove the wide electrical tape wrapped around the glass tube. This tape
serves as a gripping surface where the yoke clamp is located.
This is the limit of CRT disassembly.

Reassembly of the CRT

1. Wrap a strip of wide electrical tape around the area of the CRT where the
yoke clamp will be installed. (The tape should overlap the clear area of the
tube by about a ½ inch.)
2. Install the yoke over the CRT and lightly secure it using the metal clamp. DO
NOT tighten too firmly.
Note: After CRT alignment, a small amount of hot melt adhesive
will be applied between the forward portion of the yoke and
the CRT.
3. Install the small mu metal shield over the end of the CRT.
