How Television Invented Philo Farnsworth

[mstaton]

I found 2 roundie color sets, a 1960 zenith B&W high fidelity set with space command 400, 1 1950 philco TV and a 1949 Motorola ts18,a 1954 RCA B&W 21" TV, Not to mention a 1938 GE floor radio, a 1929 Majestic TRF radio with push pull 45 outputs, a cool looking RCA portable tube radio, a 1960 Motorola AM/FM console stereo with VM changer. There is cool stuff even in Idaho!

Isn't that what they really always did, only it's way worse today I think? Back in the 40s and 50s you could excuse much of that for the sheer nature of the newness of the whole concept from transmission to reception. But today I think they pretty much have the knowledge and technology to they point where whatever the latest flat thing you have hanging on your wall (that you bought just because something about it was said to be better) could have been produced 10 years ago.

They have learned to saturate the market in stages. First things are high priced so the "well to do" can spend big money on it; then they lower the price so the "others" can have a shot at it. Then it is "obsolete" so the whole cycle starts again.

Looking at his idea, I think he MIGHT have been off a bit on the HV supply !! 100KV!! I have NEVER heard of ANY CRT needing that much HV!! HOW would it be insulated ? 100KV will arc about 6-8 inches !! I have heard of 50KV or so industrial projo sets and some old BW projo sets were said to run up to 70KV--but not many worked out either.

But all in all--for such an early time period--he most definitely was "on to something"..

I think you didn't spot that Campbell-Swinton was proposing cold cathode CRTs so the 100kv was required. CRT technology was somewhat different at the turn of the century.
