I have 200+ schematics for OLD TVs, radios, stereos, VCRs, etc. Mostly
Sam's, some originals from the mfr. Bound 30+ per 3-ring binder for the
most part. Any takers?

for the time)--a mechanical 3-color filter was spun in front of the
CRT, synchronized to a similar filter at the camera.
It wasn't until 1953 that RCA had improved its system well enough for
NTSC color to become the official standard.
A few CBS System receivers still exist.
Lots of vintage TV's still can be found. It is getting working color CRT's
that are the problem from what I read on the net. Now might be the last time
to find CRT's for vintage computer equipment.

Has the color on modern display devices
matched the color purity of the
early TV's yet?
