This may be old hat but all the 22-5001 caps must be the
new orange ones. Also be sure you dont have one of the
terminal strip grounds loose. Most common on older sets but
with all the years worth looking at.
CRT sockets were a common problem from the tube days
on Zeniths. Usually too much focus due to a bad divider, tripler,
and or 22-5001. Also in greasy humid houses. A crude
test is pull the ground straps & see if there is voltage on them.
Use a HV probe it can be over 6KV !
All they do is ground the low end of the spark gaps on
each pin. Usually the socket is discolored or there is green mung
at the pin. If you open a bad socket its obvious.
