1974 model year.to get the best picture you would have to turn the contrast to max.this was because of the crt.blacks were black!had a friend that used that crt in a zenith flat chassis set.best picture ever on a delta gun set.these sylvanias are all gone here in central ohio.we had the largest sylvania dealer in the country back them and thousands were sold.everybody had a sylvania.they looked good,stylish cabinets and priced about 100.00 less than other sets.of course the other sets were not high leven zeniths,rca or magnavox models.triplers,ho transistors and crts were 95 persent of repairs to these sets.the crts from the lower level sets and the hybrids lasted much longer.i ve seen them go 30 years or more.they made a fine picture.the 25vdmp22 made the best picture but had a short life.
