By the way, the 23EGP22 screen aspect ratio was narrow - 1.27:1 instead of 1.33:1 (4x3). This allowed a longer horizontal retrace time without producing black bars left and right or making people look fat, which in turn reduced the peak retrace voltage on the horizontal output device. It was barely possible to produce reliable horizontal output transistors (with the required "safe area" of voltage and current), so every little bit helped.
