Philco-Ford went on till the mid 70's then was bought by GTE
who made Sylvania & soon used Sylvania chassii. During the
Ford years the TV's especially colored sets improved but never
sold well. They did make a few excellent B&W sets at the end.
The last color sets were basically a copy of RCA sets with added
unreliability. All & all they were a bit different than most sets
& added a nice diversion from the common sets you saw
day after day.
