Hi all,

I know it is a bit late as the convention was form april 23-25th.

It was a great time, got to see old fronds and meet some new ones, talk about antique televisions, oh yes and see A LOT of them :) I even came home with a trunkload of stuff.

Attached is a picture of me posing by the LARGEST direct view B&W TV the 30" Dumont Royal Sovereign.

Here is the link to the convention, I have also attached my Picsa album form the convention.

An "Iconoscope" was an early type of TV camera image pickup tube-yes-converts light to an electrical impulse so it can be processed and used to modulate a TV transmitter.Iconoscopes were sort of like a CRT in "reverse"the screen of the tube was light sensitive-as the screen was scanned by an electron beam-like in a CRT-an electrcal impulse representing the image was taken from the tube.Iconoscope cameras had a sloped or stepped front to hold the tube and lense to focus the image picked up on the tube face.I have even seen these in VERY old TV broadcast supply books.And the studios these cameras and tubes used in had to have LOTS of lighting-so the studio was VERY HOT!!The phospors on these were rather inefficient.Later devices such as vidicon and plumbicons replaced Iconoscopes-and the later devices were more compact-so cameras got smaller and less bulky.and more efficient-less studio lighting needed.
 
Sorry the reply is so late.

The convention is held every year at the Early Television Museum in Hilliard Ohio(A Suburb of Columbus) Check it out.

Oh there was a CT-100 there, in fact the set of pictures with the old color set apart, are of a rebuilt 15GP22 picture tune in a specially modified CT-100. And my "Color Bars" shot is off of a CT-100.

Attached is a 1954 GE studio monitor that used the same type of tube 15GP22.

And yes the Iconoscope needed A LOT of light, when David Sarnoff stood in front of the RCA pavilion at the 1939 worlds fair and announced that "We now ad radio sight to sound" even though he was out side on a bright day there where banks of 1KW lights shining on him.

You've heard me mention before that I always thought Color TV's from RCA had a green cast to the picture. I finally found a video that shows this.

Look at the background on the RCA set (left), see how green everything is compared to the Zenith set?
 
I never did say that RCA was best, in fact in a lot of ways other sets where better, the Dumonts where probably the best B&W sets, followed by Zenith, then Philco and RCA, Magnavox, Emerson, Motorola and of course the bottom would be Muntz. Color, Zenith,Sylvania,RCA,Philco,GE. Until the Japanese came in and in teh lat 70's Sony cleaned everyone's clock with large screen Trinitrons.

The Zenith ChromaColor II sets where amazing sets, and the System 3's where great too.
 
When I was growing up(Chicago) most people had Zenith, RCA Admiral & and occasional GE, Motorola and Magnavox. But Zenith and RCA were the top two. I would go as far as to say there were almost an equal number of the two brands. We always had Zenith sets. The last one was right after Zenith was taken over by Goldstar(LG). While the picture was ok, it always had problems of some kind most notably in the power supply. We had it for about 5 years until it caught fire in the middle of the night.

I never got a chance to actually see a Sylvania color set until I moved from the upper midwest. I think some color TV brands sold better than others in different regions of the US.

I think it's a shame that there are no more American producers of television sets.
 
Ah yes the last Zeniths, they where a discrase to the name, as where the more recent RCA "ColorTrak" sets.

The last good Zeniths where the "system 3" sets, the last good RCA's where the pre 1990 "ColorTrak 2000" sets.

Sylvania/GTE was popular around here, but it was probably Zenith,Sylvania,RCA,Sears,Admral out here in Youngstown.

I am about to go rescue an RCA roundie color, a Sylvania and a few nice B&W sets form being thrown out.
