DeLoss Tanner died (cerebral hemhorrage, IIRC) just before I got out of school and joined Motorola. I inherited a different project of his, a transistorized black and white TV that was an experiment in cost reducing any way conceivable. The set was breadboarded on a tinplated steel sheet. My first job was to buy a car battery and charger to run it. The IF transistors had no emitter degeneration and were current-biased by the AGC circuit. The CRT had been built from a cut-down glass milk bottle, with the bottom of the bottle as the screen. You could read the dairy's logo, stamped in the bottle bottom, in the picture; and it was, well, "milky" looking (no aluminization). The set basically worked, but there was no hope of holding tolerances for production. I got it running, and it went into storage or maybe got trashed, I don't recall; but at least it then was a documented experiment.
