A friend of mine has his Transvision that he built in '45-'46. It is in the same configuration as seen in the above photos. He told me he built it without a multimeter, as he could not afford one. When he did the initial powerup, he had no raster. By modifying a photo light meter into a continuity tester using a 9v battery, he tested all of the hv resistors until he found one that was open, and cured the problem.
