Represented by AM Radio Sales Co, Westinghouse Broadcasting Co., Inc, BIG TEST FOR IMAGE ORTHICON New tube successful in color baseball tv One of the last remaining gaps in color telecasting has been closed. The gap has been the inability of color camera tubes to operate with less than bright, bright lights — particularly the impossibility of picking up night baseball games and other outdoor night sports in color. The new color tool is a highly, lightsensitive image orthicon. GE already has one on the market and in use. RCA last week announced that it has one available. The GE tube received its severest test last Monday night (May 16) in the WLWT (TV) Cincinnati color pickup of the night ball game between the Cincinnati Reds and San Francisco Giants. Good Showing ■ The color values seen on color receivers in Cincinnati were considered as good as anything seen on studio-controlled color broadcasts. The showing was staged by the WLWT’s color-active Crosley Broadcasting. Co. (Broadcasting, May. 16), which previously used the tube in covering Palm Sunday and Easter church services and in local basketball games. The GE tube, developed principally for military surveillance, works well with one-third of the lighting normally required for colorcasting, Howard Lepple, WLWT chief engineer, explained. This would be from 100 to 200 ft. candles, he explained, and cuts costs of highlighting and airconditioning. Mr. Lepple is credited with “discovering” the potentials of the GE tube when the company sent it to him earlier this year in answer to his request for a camera color tube capable of picking up night ball games. The tube sells for $2,025 and Mr. Lepple has 20 for use with his six color cameras. He estimates he has some with over 1,600 hours of use (compared with normal 1,000 hours for regular black and white tubes). Principal element in the GE tube is a wafer-thin, magnesium oxide target. The GE tube is also in use at WGNTV Chicago, KTNT-TV Seattle, WSJSTV Winston-Salem, WCCO-TV Minneapolis and WIMA-TV Lima, Ohio. It was demonstrated at the NAB convention last April. No Greater Lighting ■ The RCA tube development (RCA-4401) was officially announced last week by RCA President John Burns. Mr. Burns, addressing the company’s western distributors in Las Vegas, stressed that the new tube requires no greater lighting for color than for black-and-white. He said it had been tested successfully in Boston. Mr. Burns said that NBC has ordered four sets (three matched tubes per set) and that WGN-TV had ordered one set. In specifications sent out to RCA sales engineers the new camera color tube is said to operate effectively at 40 j| ft. candles with an f/5.6 stop. Price i was listed at $1,900 per tube.
