IIRC Zenith EIA will be 343 or 1101
Thompson/RCA I think still used 274 EIA code.
Bonded yoke sets used connectors on the yoke itself,
non bonded plugged in right on the chassis.

Would anyone be able to tell me if the following 2 Picture Tubes would interchange for an A68ADT31X03?


1. A68ADT19X01

2. A68AEG20X02

There was out in internet land a site that told what
the numbers meant but I only found it once.
Almost any modern CRT will have almost the same
electrical specs. When you can decode the part # you
can find what the differences are. They may be........

bonded or non bonded yoke.
pin out
max HV
face glass color / transparency
physical shape / mounting
implosion protection
screen size
phosphor type
& more.............

For the first step ID the jug. Post clear pics of the CRT tag &
the yoke area. Since most CRT's from the same mfr are the
same this will narrow down your search but also widen it to
other brands that may have used it.
