Default 819 line TeleAvia

Hello,

I don't make progress in English but..

I've just finished restoring one of my Teleavia P111, it's 819 lines.
Now it produces a nice picture.

It works with the Aurora converter

Sincerely as always

wilfrid

The Teleavia is a truly wonderful looking set. Just like the Philco Predicta the cell that houses the CRT follows the shape of the tube to good effect.

Those 819 line pictures look really good, thanks to the availability of the Aurora converter we can now display this high definition standard.

Congratulations to Wilfrid for a superb restoration job.

This television set was made between 1957-1959.

This model date of 1957 in fact the first model was made all in metal and the second was made in iron and composite.

I've the two models. I think you want to see more inside so I join picture.

The chassis based on the Pathe Marconi; it's nearly the same except for power Pathe Marconi uses 2 valves Ey82 and Teleavia use a "redressur" (sorry if I can translate correctly).

A lot of people think it's a copy of a Predicta but this television set was draw by Philippe Charbonneaux. I've no idea who drew Predicta, but I would like to have also this television set.

At this day we don't find the original Teleavia diagram but finding diagram for the Predicta is easier - I have it !.

Some picture of the chassis

sincerely with all

wilfrid

Great - well done! I love those creamy-smooth 819-line pictures...

Redresseur translates as rectifier.

819 was indeed an early attempt at HDTV, that's HDTV according to the modern reckoning. It was a bold step but unfortunately was a little too far ahead of it's time. When M-EMI decided on 405 they knew they were taking a big leap ahead, hoping the technology would catch up. Presumably the inventors of 819 took a similar view but history offered a different judgement. 819, even interlaced, would just about fall within current HDTV definition, where the lowest standards are 750 lines (720 active) but without interlace.

I wonder, did the original 819 line standard include equalising pulses, and how good was the interlace actually in practice? Even a line-paired ('true' 409½ line) picture would have looked pretty smooth.
