Great video. You could teach a course in safe and effective troubleshooting.
I worked in a shop 1981-82 when these were coming into the shop with this problem...from the warehouse! 1976-80 Sylvania-Philco sets had nice pictures too, but I was not happy when NAP acquired Magnavox.
Nice use of the VA-48. my VA-48 needs some help, now I'm motivated to fix it.
I have a Heathkit HV-meter w/ ring test that does something similar with 6 positions. It was almost never wrong.
