more photos as seen in TV studios in the 1950's and '60's

"Mr. Television" himself, Milton Berle, poses with a TK-41. Looks like Uncle Miltie is pretty excited about being seen in Living Color for the first time!

TK-40 assembly line, 1954. On the right rear of the camera body, the split, circular opening is an air vent for one of the image orthicon pickup tube. There are two additional vents on the rear of the camera.

Nanette Fabray sings in front of a prototype color camera, 1951. In late 1940's-early 50's, RCA was continuing to develop their color television camera (which eventually became the TK-40 introduced in 1953).Notice the script on the side of the camera says "RCA Television) (versus the TK-40/41 which had a "Color Television" script). Also, the camera is black (versus the silver colored TK-40/41), and there are no vents in the viewfinder on top of the camera. The TK-40/41 tapers to a narrower width at the front, where as this prototype has flat sides with no taper. I would speculate that the production camera used a silver color to reflect the heat which would have been absorbed by a black camera. After all, the early color cameras required a LOT of light - without plentiful air conditioning, the studios would be unbearably hot and the cameras would suffer performance problems from overheating. This would also explain the slotted vents which appeared in the TK-40A and TK-41 cameras.

The last incarnation of the TK-40/41 series was the TK-41C, seen here at the 1962 NAB (National Association of Broadcasters) convention. This photo is from the May 1962 issue of RCA Broadcast News.

"TK-41C color TV camera, standard of the industry. New features for 1962 include stabilized circuits for simplified operation, precision yokes for precise registration, and prism optics for sharp clear color pictures."

Uh oh, a suitor waits in the wings! The TK-41 will soon be replaced by RCA's new TK-42 "M-channel" color camera. In addition to the three color (RGB) vidicon pickup tubes, the TK-42 adds an image orthicon monochrome fourth tube. Shown here is the TK-42X experimental camera and a TK-60 monochrome camera at the 1962 NAB convention.

"One of the first sights to greet visitors to the RCA exhibit was the operating live TV studio and an introduction to a new generation in broadcast equipment."

The production TK-42 color camera

(Webmaster note: my memory of this camera is that it produced inferior pictures to the TK-41. The images were noisy (grainy), and most irritatingly, the built-in zoom lens produced erratic zooming motion. The zoom was operated by a crank on the rear of the camera similar in appearance to the old turret handle on the TK-41. It must have been awkward for the operator to zoom with this type of control, and the mechanical cable connecting the zoom control handle to the lens was subject to binding, invariably creating jerky, chattering zooms.

Rear view of the TK-42.

Notice the infamous U-shaped lens controls on the back of the camera. Left handle is focus, right is for zoom motion. Chattering zoom motions plagued the TK-42 from the beginning. The TK-43 was basically the same as the TK-42, but with a new approach to zoom and focus controls. NBC chose not to install TK-42/43's in their network operations. NBC's old TK-41's continued to produce superior pictures into the early 1970's, partially due to modified low-noise transistorized pre-amps.

The RCA TK-44 (seen here at WTMJ-TV Milwaukee) was finally a worthy successor to the TK-41. The TK-44's plumbicon tubes produced rich, crisp, clean color images. NBC network facilities finally replaced their TK-41's with these excellent new cameras.
