Replaced C3 multisection. You can see its replacement at beginning of video, right behind CRT. Also made adjustments to yoke, vert lin and height. Previous strange loud noise has been eliminated. Vertical oscillation was definitely getting through the audio section.
Still need to go through the components on PCB board. Set is only passing audio and no video at this point.

PS the plastic yoke cover has disintegrated and I had to remove it. The yoke is essentially floating on the neck of the crt. I'm thinking I'm just going to fasten a couple large plastic zip ties to hold it in place (?)
