Hello 21C1, In the video it's a modified GM UF just made on some matrix board to see if it's any different from the original version. You can see the three circuits here: https://www.scottpages.net/ReviewOfControllers.html
Also a 'taster' here: https://ogaugemicro.blogspot.com/p/controllers.html with a comparison of the above and the Brian Tilbury pulsed/feedback controller using similar components. Both have the same superb control and are from the 1970's.
If you or anyone else would like my PDF which assumes no knowledge of electronics, please send me a nice message it does take time to author the PDF's I send out and now I ignore one line phone speak demands.
Cheers - Jim
