When the first all transistor black and white tv? 19 inch
I found this Philips 19TX430AT in the Netherlands, here it is the first TV where no tubes were used, only one for high voltage rectification. This model came on the market here in 1964, mine is from February 1965.
The TV has a 19-inch picture tube and can also be used on 12 volts DC, but also has 220 volts AC. These TVs are very rare here in Europe, the new price was very high. Now the question, were there any other manufacturers in that period that made all transistor TVs? It took until the early 1970s for the tubes to disappear. They were manufacturers in the 60s that made all transistors, but they were mini TVs. But a 19-inch all-transistor TV from 1964/1965 seems very special to me. See my website for more. http://www.marcelstvmuseum.com/Phili...1965%2001.html http://www.marcelstvmuseum.com/Phili...1965%2009.html

Very interesting set. The 1964 BRIONVEGA ALGOL 11 has 29 transistors, and 1 regulator tube.

Wonderful site you have. Plan to spend more time with it. Always liked B&O design. Last edited by etype2; 05-21-2022 at 02:35 AM.

From about 1965 19" solid state B&W I remember were from
Zenith, Motorola, Westinghouse, Magnavox & I think Sylvania. I only remember a 12" RCA which is surprising. Sets from Japan were all 12" & under. Here is an interesting Zenith ad for the smaller set. https://www.youtube.com/watch?v=IgzYj5_mlxg The 19" was also hand wired on a steel chassis with plug in transistors. Quite rare due to cost, I have only seen a few. 73 Zeno  LFOD !

I think in addition to the Safari, there was a Motorola Astronaut, which was probably the first "big screen" solid state TV, in the earlyb60's.
Both Philco and Motorola made TVs, and Philco still had an active semiconductor division. Which I think got killed off in the 60's. Speaking of which, I missed the ETF this year, but I'm curious - did the Predicata really kill Philco off? (I suspect it was a few factors, including the above-mentioned semiconductor division, which IIRC, invested heavily into surface barrier types, right before the mesa and planar types were developed by others)

You're right about the Motorola Astronaut...I think they were 1961 or 62. The guy that helped pre-teen radio collector me learn repair told me that when he first saw a moto astronaut it was sitting on a table running, assumed it was a tube set, and his jaw hit the floor when the owner picked it up and walked away with it still running (off batteries)!

Philco did some nasty things. You couldnt get parts wholesale,
you had to go to a dealer. The predicta & latter sets like the seventeener were the most un serviceable made & not so reliable. Add to that those damn couplets & you get a set that both dealers & techs detested. This makes for dealers dropping the line. As the 60's rolled on they did get better & built a real nice color hybrid that goes unrecognized by most. Attempts with SS sets were bad ( cloned RCA SCR sets). One exception was a little space age B&W that was quite nice they made at the end. 73 Zeno LFOD !

You can access videos of the ETF presentations and other activities here.
