That's for the HC tube chassis Portacolor. They were not produced at the Portsmouth plant, but at the Utica or Syracuse plant. What Jerome has is an AA-D chassis, all solid state, often referred to as a PortaColor III - a tech term, not a GE marketing term.

The AA/AB/AC chassis was GE's third attempt at making a universal chassis similar to the Hitachi, Toshiba and NEC sets, where one chassis could drive a 13, 17, or a 19" set. Yokes and CRTs aside, they were all basically the same for a given chassis series. The first two GE attempts were the YA and the EC chassis sets, both modular chassis sets. GE had so many module variants that they had something like 210 different modules - EP93X40's to to EP93X300's. That, plus the Hitachi-based projection stuff they started out with, and it was hell stocking a working supply of modules. We had a three-page module matrix listing at the GE distributor I worked at in 83-84 - it was worn thin by the time it got updated. So much for universality....
