ends of
the bolts,
and fasten them firmly with
another
set #2-56 nuts. Place a
drop of red
glyptal over each of the second set
of nuts
after
fastening.
Mounting
Later
Ceramic
Strips
To
replace
strips
which mount with snap-in
plastic fittings,
first
remove the original
fittings from the chassis. Assemble the mount
ing
post
on the
ceramic strip. Insert the
nylon
collar into the mounting holes
in the
chassis. Carefully force the mounting post
into
the nylon collars. Snip
off the portion
of the mounting post which protrudes below
the
nylon collar on the reverse side of the
chassis.
Note
Considerable
force may be nec
essary to push the mounting rods
into
the nylon
collars. Be sure that
you
apply
this force to that area of
ceramic strip directly above the
mounting rods.
Color
Coding
All
wiring
in the Type
CA Unit is
color
coded
to facilitate circuit tracing. Specific
color
codes are used to distinguish the leads
for
the
power-supply voltages obtained
from the
oscilloscope.
These power-supply leads
follow
the
standard RETMA code. The -150 volts
bus wire is coded brown-green-brown; the
+ 350 volts bus is coded orange-green-brown;
the
+225 volts
bus is coded red-red-brown
and
the
+100
volts bus is coded brown-black-
brown.
The widest stripe
identifies the first
color
of the code.
