Description

%StinghOllSé 14AZP4 1 April 28, 1959 RADAR DISPLAY TUBE TYPE 14AZP4 The 14AZP4 is a magnetically focused, mognetically deflected cathode ray display tube. Its high resolution gun coupled with high brightness capabilities make it especially suited for high resolution monitor applications. The face is gray-glass for improved contrast and the screen is aluminized for increased brightness. ELECTRICAL: MAXIMUM RATINGS Cathode. . . .. v v v v i i e i e i + ..
