gray vs dark gray CRT screen

[sampson159]

sylvanias 25vdmp22 was considered the best looking crt back in the 70s.they produced the absolute best picture but they didnt last long.3-5 years and they were gone.their earlier 25vamp22 crts seemed to last forever.these are delta guns.the ultimate set would be a flat chassis zenith with the sylvania dark matrix crt.the zenith chromacolors were the first black matrix picture tubes.
