The RCA 913 is an electrostatic deflection CRT with a tiny one inch screen. This octal base tube has a curved spherical screen and an unusual metal shell, instead of the glass neck seen in most CRT's. The 913 was specifically targeted at the hobbyist and experimenter market, and had a selling price of $4.00 in 1936.
