Dumont 3BP1 / 1051P1 / 3ABP2 Double Beam CRT Cathode Ray Tube With Padded Case

Dumont 1051P1 / 3ABP2 Double Beam CRT Cathode Ray Tube With Padded Storage Case Up for sale is a Dumont Cathode Ray Tube. This is old US Navy stock, and were used in oscilloscopes and radar systems. This is a two-gun electrostatic deflection CRT, capable of projecting two beams at once. The tube's 3-inch screen is coated with a high persistence green phosphor. Though the separate guns share a common heater, each gun has it's own set of deflection plates and can be independently positioned. This feature makes it a favorite for homebrew electronics projects, as each beam can be dedicated to drawing a different portion of the screen. CRT will be shipped in a metal padded storage case which is made to hold the tube. Please see photo's for personal evaluation and specifics. Thanks for shopping with us!
