Can somebody point me towards books, websites, or published journal articles that fully explain deflection output stage amplifier design?

I have been reading Grob's "Basic Television" textbook. Bernard Grob was a head engineer and instructor at RCA during their golden era, when RCA was pretty much inventing every technological innovation in television.

The third and fourth editions of "Basic Television" are great as they cover black and white, color, tube, and solid-state TVs. Grob explains in sufficient detail everything about a TV needed to build a custom circuit from scratch... everything except the precise output voltage and current parameters for the output stage of a deflection amplifier.

Grob gets VERY close, describing the details of how to design sync separation, phase detection, oscillator, sawtooth waveform, and he covers the high level design of the power amplifier output stage... but when it comes to the exact formulas to use for the deflection output stage amplifier and impedance matching transformer, specifically the output voltage and current needed to deflect the raster by X-degrees horizontally and Y-degrees vertically... he just doesn't provide the necessary details.

I am looking for enough detail to DIY a custom tube TV circuit from scratch. Similar to the amount of detail available in the DIY tube audio community, where it is clear how much voltage and current the audio amplifier's output stage needs to provide to properly drive a loud speaker with a given specification. So if you have any pointers, even a retired TV engineer that I should try to contact, please help! I want to try to spark a DIY TV community by building a custom TV circuit and publishing the designs open source, similar to the DIY tube audio community.
