Cathode Ray Tube Projects #1, Testing a Mystery CRT

Today, Labguy takes a break from the cameras and sync generators to play with a really cool compact "picture tube" that he has had stashed away in his junque collection for far too long. Time to fire it up and see if it works or is just another useless nick nack. The tube is the M1234P31 made by Electron Tube Division of General Atronics Corporation. This tube is a cute three inch by three inch blue/green phosphored type that is a mere seven inches deep. Utilizing magnetic deflection and electrostatic focus as well as having an aluminized phosphor screen. This tube would have made a very bright display with a very long service life and low burn in.
