Refer to Detail 4-3D and mount a .001 pF ceramic
capacitor
(#21-165) at CM on the inside of the RF
SOLDER LUG
shield (this capacitor may be marked 1000 MMFD).
Use a 6-32 x

Refer to Detail 43E and install the zener diode at CW
on the outside of the RF shield with the mounting
stud and nut on the same side of the shield as the brass
spring, as shown in the Pictorial. Cut
a
slit in the
silicone grease pod
(#352-131, squeeze out some

grease, and with your finger coat both sides of each
mica washer before you install
it.
Make sure the nylon
