High level de-mod, and some interesting color sync circuits of their own design.
Corrections and comments welcome!

Admiral offered 5 models in the '56-57 model year. The models ranged from $499.95 to $829.95 depending on cabinet style, finish, number of speakers and UHF option ect. The Ambassador was a mid priced console in the line up. All models used one of three chassis in the course of production: 28Y1 (early 1956 production), 27Z1 (mid production) & 29Z1 (1957 model production). All were similar w/the numbers reflecting running changes during the production run. The chassis, as you mentioned, used high level demonds which eliminated costly & complex matrix circuits and along w/ several dual function tubes provided lower production cost. This "simplified chassis" design somewhat mirrored RCA's "simplified" CTC-5 chassis but was designed by Admiral and not an RCA clone. Pictured: 1957 Admiral top of the line "Patrician" model.
