It was based on a 12" record, a neon indicator valve and a selenium
photocell about 1" square and around 32 cheap plastic lenses.
A small transistor amp based on a BC 108 in a tobacco tin gave me a bit more
gain and I recorded all my "programmes" onto audio tape.
I always had sync problems and the picture splitting.
At one point, I tried to transmit a "live programme" to a mate with another
televisor/camera via CB radio.
Guess what, it failed. We put it down to the bandwidth being 12 KHz and the
CB channel only being 10KHz. Nothing to do with noise, QRM or a complete
lack of sync pulses.
Hope to help you best I can.
Best of luck.

I built my first televisor/camera back in around 1980/81."Zoe" <Zoe@Safestars.com> wrote in message

I'm intersted, but more reading about rather that building nowadays.
