I had a heck of a time with arcing in my Zenith Porthole TV.
Turned out that the arcing was between two pins in the 1B3 socket
and continued across the phenolic board to the chassis.

Replaced the 1B3 socket with ceramic (thanks to the forum member who gave me one)
and then cleanned and drilled out the carbon on the phenolic board.

When I pulled the 1B3 tube, I observed a carbon trace between two pins -- check your 1B3
and areas on the phenolic board. Might have to clean the phenolic board of all the
decades of duct and dirt.

Then, I when I reinstalled the new 1B3 socket, I was not careful about sharp points.
My first attempt at a TV restoration and I was learning.
I had to go back and cut off the resistor and wire tails, blob a smooth coating of
solder, and paint Corona Dope on some places.

I did not find arcing inside my Flyback.
