John, pictures of my build are here: https://ik1zyw.blogspot.com/2020/10/kit-oscilloscope-clock-8sj31j-review-3.html
The code on the HV board is the same. I think I reversed a 79Lxx, but the smell of it burning was too obvious and I cannot tell what the effect was on the CRT. I do get intermittent failure probably caused by a cold joint at a ground point that was not designed with thermal relief and it took me a while to solder.
