This instrument uses the RCA 906 3′′ tube and offers a large, clear image without expensive accessory equipment as required for larger tubes.
All the controls, including the spot centering controls, are on the front panel. They are of the bar type, easily adjusted. Smaller size and lighter weight greatly increase the portability of this instrument. And its new styling, flexibility of operation and finer performance make it unusually attractive.
