The impact of early color
In my lifetime I have witnessed many amazing things but not one of them compare to seeing a color television in the 50's! It was almost sirreal
I can't say that anything has even come close since then

and the kicker was for the most part, they got it right. witnesses by the fact that many of the early color sets restored produce a picture that rivals many of today's versions. (analog anyway)

Consumers traded out the early color TVs mainly due to reliability issues. Even the best ones burned through horizontal output tubes, dampers, rectifiers, circuit breakers, convergence board coils, flybacks and vertical components on a regular basis. People watched them several hours every day so things overheated and boards got brittle. Eventually it was fix the TV again or buy a bigger boat. Few could afford both.
Those unreliable components were engineered out one by one. Each generation improved until the current generation of solid state TVs is sufficiently reliable that it required FCC regulations to mandate a trade out. That's what HDTV is all about. |

I wonder why more was not done to improve the tube type color sets. I know about the problems as we used an RCA CTC-39 for 10 hrs or more a day when I was in high school. Bad solder joints, horizontal output tubes burned out etc. Parents had to buy new TV's when I moved out as the "TV technician" (ME) was not there to take care of the sets anymore. They do take a LOT more maintenance that solid states when they are used a lot. RCA seemed to be the worst with heat destruction of parts. The Zenith hand wired chassis seemed to be the best with regards to heat related problems.

My first color tv...
Hi, this is my first color tv. My parents bought it in 1969. It was very uncommon seeing color televisions here in Italy until regular color broadcasting started in 1977. The interesting thing is this is a genuine handcrafted Zenith tv made for Pal B/G tv system (you may notice it completely lacks hue control). It still works quite well for its age!

Was this a commercial PAL set, U.S. export, or did somebody modified a NTSC set for PAL broadcasts? Eckhard |

On 10 August 1970 could see some Florentine football matches of the World Organization for the first time in color, and for the first time ever not in connection with a broadcaster of State, the same place of Mauro Montagni company was transformed provisionally into a hall to watch the games in color. Only after the heavy defeat in the final 4 to 1 with Brazil the Judiciary intervened against contractor had infringed because a law of 1938 that forbade anyone to make radio without prior authorization from the Minister of Posts. The same Montagni recalls, with much regret, that to see the matches in color at his company were the Mayor of Florence, the Prefect and also the director of RAI Florence. <<Tutti To tifare as amiconi old data; pity that they finished the World Cup I denunciarono>>. A lawsuit that Mauro Montagni lost, but at a distance of more than thirty years can proudly claim to have won and quest'episodio gave way to long and arduous struggle for the spread of private television over the air in Italy.>> <<In Italy are beginning to receive foreign television signals as: TV ITALIAN SWISS (IST) from the Canton Ticino, TELEMONTECARLO (TMC) from the Principality of Monaco that radiates the first transmission to Italy on 5 August 1974 by the 'Industrial Marcucci who install a repeater on Mount Pizzorne in Lucca, KOPER KOPER TV station upstream Nanos in Yugoslavia and ANTENNAS 2 (A2) from France. The latter, so that the signal was received well throughout the central and northern peninsula, demonstrating the superiority of television system colors French had stipulated by the company INTERSECAM, a costly maintenance contract with the Florentine businessman to Montagni which were provided all the equipment necessary radio frequency.

Hello everybody! Yes the Zenith I have is an almost all tubes set. Despite the fact that it does not have the common "chromacolor" logo on it,it is equipped with a black matrix tube. It also has the common handwired metal chassis. Not many color pograms to watch at the time. I think my parents bought it because at that time there were rumors of incoming color broadcast. I remember watching experimental color tests at that time as well as the olympic games but nothing more. It is not a modified set, it is all original as manufactured by Zenith. I will try to make photos of the inside. I had another Zenith color tv (chassis 24MC32). It was a round tube set modified to be used with our tv standard. I recall it was bought by my grandfather during the sixties. Zenith was a very popular brand here in Florence during sixties and early seventies as there was an importer who used to import them directly from the production line and then modify them. I remember not many years ago I contacted that man and he brought me to a warehouse where there were many round tube color tvs still in the box together with chasses of equally old sets pehaps used to pick up spare parts and many many other old bw and color Zenith tvs!!! All that has been trashed not more than two years ago...What a shame!!!

Manufacturing costs drove the migration to solid state. In consumer products, the driver is unit cost. Little else matters. Transistors enable simpler power supplies, no sockets, automatic insertation and low cost. Everything else follows. Cost! Cost! Cost!

In total these late 1960s were very exciting times, it was the time of the moon landing, color television, The Beatles and so on. But with respect to media events, I think color television was the greatest revolution since introducing of television, and no other new media can keep up with it. Eckhard |
