The high voltage deflection amplifier turns out to be a classic Class-AB design. Some techniques (e.g. the degenerated differential connection) are used to enhance linearity. I don't think in its design there are any advanced techniques like bootstraping.
This system is open-loop in nature. I saw markings on the sensitive transistors (especially the differential pair), indicating that those transistors are hand-picked to improve matching and accuracy. The overall gain should be 13~17xWX-10 HV Amplifier Photograph WX-10 HV Amplifier Reverse-Engineered Schematic
