Actually what I was tryin' to express in the OP was not about synchronization, but rather would pertain to a free-running vert or horiz sweep amplifier without any sync input to the oscillator.
What design factors combine to produce a nice linear sawtooth wave (as opposed to a sine wave or 'humpy' wave) across the yoke winding (or to the deflection plates in an electrostatic set)?
I gotta confess to having spent a whole 'career' in the trade without having heard a good synopsis on just how the sawtooth wave gets produced. It was always one of those 'givens' that's always taken for granted without question. Sorta analogous to an auto repair techie not pondering the chemical minutiae of fuel/air combustion.
