Thanks for clearing up the choke NoPegs, just this tech is so much older than even I, but a lot of fun to learn so far.

I did include a couple of pictures with what I will refer to as the "Spark Gap" because I researched for two solid weeks and couldn't get a solid answer or definitive explanation of what it was. I only found one other picture on the internet with a old tv that had something like it installed. This old monster has two HV wires coming from the top of the tube, one goes to the Glass AMP hooked in with the Flyback, the other goes to our mystery "Spark Gap".

Essentially it had a hollow ceramic core and two metal leads going on under the plastic cover.
It was scorched inside and broke the moment i touched it. From what I can tell is that it wouldn't conduct, unless voltage present at the upper end was strong enough to arc from one lead to the other, forming a low resistance path to ground once the arc had started until the breaker tripped or the over current condition passed. From what I can tell these were used as lightning protection for the CRT in some models.
This "Spark Gap was clearly conducting and for a good while cause I could hear it "whine" while it was arcing and smell the plastic burning from it.

rca2000, the choke just looked like it got hot to me. it felt like burnt paper to my hand. I just don't know. It probably isn't bad, but I was trying to cover all the bases.

And if it is just a fancy resistor that went bad I would be so pleased to know it can be replaced! Been banging my head against the wall for a while with this and really appreciate the help from both of you! Thank you. It means a lot and helps a lot to get this advice.

The pictures are of the "Spark Gap" that I know is broke and cooked real good.

Again thank you!
