Here's a 1982 19" Sylvania color TV that uses the E32 single board chassis. Being from '82, it was made after GTE sold out to NAP; but, the chassis is an original GTE design that was carried over after NAP bought them.
The cabinet style seems to be a carry-over from the '70's and I've actually seen the same cabinet used on some later Magnavox, Philco, and Sylvania TV's that used the NAP designed 19C3 chassis.
This set came from a TV shop with a note indicating that the flyback transformer is bad. I have not tested it yet to confirm the condition of the transformer.
From what I remember of these sets, they produced a decent picture.
