There's usually 2 vertical stage "K" networks (aka RC couplates) one is used as the vertical integrator for the sync, and one is used as feedback from the very out plate to the first stage of the vertical multi vibrator....If it goes bad it can kill the vertical, cause linearity issues or the vertical can stop and start with weird linearity issues throughout....I had a roundy where a previous tech put in too low of voltage rated micas in their replacement for vertical feedback and it was a PITA to troubleshoot.

Thank you there are 2 K networks in my vertical. I'm guessing it would be the second one closest to the vertical transformer that would be the issue?

Just a thought I'm pretty sure I ordered Discs incase I had to build these. Should they be micah?

C0G ceramic should be fine. I have a hunch the lower voltage micas that were shorting were chosen because they were whatever the previous repair man had on hand.

These couplates are integrators as I mentioned earlier. Google the part number on the disc and you will find their values and you can make them out of discreet parts. Very troubelsome critters
