Picture Tubes
15GP22 Color CRT
The 15GP22 was the first production color picture tube, made in 1954. It was used in the RCA CT-100 and most other 15 inch sets made in that year. The CBS 15HP22 was similar, but easier to manufacture. The 15GP22 was quickly replaced by the 21 inch 21AXP22, which was used in the 1955 model sets. Here is an article about installing this tube. This tube has now been successfully rebuilt by RACS, a French company.
