Sylvania made some combination console TV's in the late 60's that had
electronic 35mm slide viewers. These used, I believe, a small aperture B/W
flying
spot scanner that back illuminated the slide into a set of transmission
beamsplitters to three separate color pickup tubes. Your old tube may be a
custom
built component of that system. From the way it is described, it may be one of
the
pickup tubes. The plate in the tube you describe may be a photon sensitive
grid control plate. A photon detector. It could also be a beam detector used in
a doorway sentry.
