Need better picture of degaussing - PowerPoint presentation

I'm doing a rework of a nostalgic talk I made 3 or 4 years ago on TV-DX and the "Joys" of television ownership in the heydays of CRT televisions. That of course includes the need to manually degauss color tubes. My first color set was a 1976 Heathkit GR-371.... It was a transistor set but it still needed a good "wanding" with a hand held degaussing coil about every year before tweaking convergence.

The only on-line photo I've found illustrating the process shows a generic computer monitor of the 1990s. I'd like to have a photo showing the "wanding" of a 50s or 60s color set. I went thru a number of YouTube videos seeing if I could do a decent frame grab, but found nothing...

Any chance you have a picture to share?

Thanks,
Robert

There are a lot of degaussing videos on YouTube. Maybe you could ask someone if you could use some screenshots from their videos.

I mentioned above that I have already trolled-through the numerous YouTube videos... There might have been something I missed, so that is why I made this post...

Robert, I'd think that any older color-TV servicing book would have a good illustration. Alas, all my TV-servicing books are pre-NTSC color, and I find that my Heathkit GRA-227 manual is missing many pages. Sorry!

Shango066 did a degaussing recently. https://www.youtube.com/watch?v=anXLhlAefG0 At about 1:09 You could ask him for permission.

Thanks for the link.... The frame grabs I could do just are not good enough to illustrate with a single image... His camera crops the view of the degauss coil too much. No shade on him though for doing what he did... It worked for his presentation...
