Dang, this puppy's got some interesting early circuit topologies. The CRT is driven with video at the grid instead of the cathode, and brightness control is done via the cathode, the reverse of later standardization. And AGC is via a simple detector-driven, non-delayed type just like the AVC (automatic volume control) circuit in AM radios. And the damper is placed differently in the flyback's DC path than in later standardization, wherein B+ is supplied directly at the damper's plate.

Interesting study in the evolution of TV design.
