Coincidentally I was reading the chapter about video amplifier circuits, peaking coils, etc. just a few hours before I saw your post.
Anyway it's called Color Television Principles and Practice, by R. R. Gulati. Don't worry the book covers B&W in extreme detail before it even touches on color. I think it was originally a textbook used in India and the color stuff deals more with PAL than NTSC, but again the text is system-agnostic. Maybe it's a good resource to check out if you're stuck on something. You can buy it on Amazon https://www.amazon.com/Colour-Televi.../dp/8122400086 or since it's out of print you can download it for free as an ebook from Libgen. |

I just flipped through the PDF copy of the second edition of Gulati. It was published in 2005 and yet still has in-depth coverage of pre-solid state TV design! Amazing! Also it seems to go into depth of the transient response formulas for the deflection circuits. Sadly in the USA, television circuits books published after the 1970s had all vacuum tube circuit theory removed and went pure solid state (of course except for the greatest vacuum tube ever, the CRT).
I am almost done reading Kiver. I am placing his text up in the top tier with Grob's text. There is a reason why both authors had their TV circuit design textbooks published over and over again in several editions. They are just plain great!
Getting the same theory explained by different authors is useful when teaching yourself. Sometimes for stuff to resonate with your brain, you need to have it explained multiple times by different people. Also, Grob and Kiver use snippets from real life popular models of RCA and Zenith TVs. Since they use different example brands and models in their books, reading both books means you also get to study more example real life circuits. That is another important thing. Learn the theory and study real life applications of it.
I now have a pretty good understanding of how to adapt both vacuum tube based vertical and horizontal deflection circuits to be able to drive a late 1990s diode split flyback transformer and late 1990s low impedance yoke (0.4 mH and 0.9 Ohm horizontal winding) and its matching ultra fine dot pitch "M-class" CRT. What I need is a small high efficiency ferrite core 20 to 1 transformer that steps down the plate voltage by 23 to 1 and steps up the current by 1 to 23 is what is needed to translate the high voltage, low current output of the beam power tube to the low impedance yoke. The ideal would be for these two windings to be on the diode split flyback transformer, as that would be more efficient, but for my first design, I wanted to stick to a "modern" diode split flyback transformer because they are super reliable and safe. Yes these diode split flyback transformers have 3 built in semiconductor rectifiers, so my TV design will have semiconductor rectifiers in the high voltage power supply... but I am also going to use a semiconductor rectifier in the B+ supply too, at least for my first DIY tube TV. In a later revision, I will try to modify the design to not use any semiconductors, but for the first version, it will be pure tube in all signal paths and a few rectifiers in the power supplies to convert from AC to DC.
Regardless, I want to refrain from circuit designing and circuit simulation until I finish working through the reading list. No reason to reinvent something that is written in one of these textbooks.
