Remember, the original Lawrence Tube renamed Chromatron was developed as BOTH one and three gun CRT's by Chromatic Television Labratory Inc. starting in 1951. Dr. Lawrence partnered with Paramount Pictures and Chromatic was a division of Paramount. Chromatic always knew that a three gun Chromatron would be considerably brighter then a one gun, but the one gun version received all the interest because of the potential simplicity of operation and lower manufacturing costs. Prototypes of both one and three gun versions were made through the years, then Sony bought the license and development rights from Paramount, first in 1961 and 1964.

Nothing against this highly informative and interesting thread, but frankly I'm surprised that it hasn't been moved to the rectangular forum. Again very interesting.

That clunking SL-5000 Betamax came out in 1981.. Those have a handful of defected electrolytic caps on the servo board which cause unstable playback between the drum speed and tape speeds..

We had a profeel customer with a large monitor that we kept taking back to the shop for a shutting itself off symptom. I forget the size of the set but I want to say at least a 21 inch or larger. That was a heavy monitor. I think we had it back and forth between the owners home and the shop at least 3 times. Even put heavy blanket to try to get it to heat up. We finally did get it fixed. It was the HV shutdown circuitry that was detecting arcing in the HV block. A new HV block fixed it finally.
