Tnx findm interesting stuff. Another Zenith one was the spark
gaps used in late CC2 & up. It actually worked !
We found sets hit by lightning where it was melted & blackened
but the sets kept running. Only found out when the set was
opened for other unrelated problems.
Lightning work used to be gravy work. Only had one Admiral
destroyed by a direct antenna hit. It blew a PCB to shreds.
When cable TV came along it became the great destroyer of
TV sets. The ground for the cable completed a circuit that common
power line hits could use to send a huge surge through everything.
