Simply amazing restoration Eckhard! That is one of the finest examples of ETV you have there. I'm glad there are others out there taking care of these beauties.

Beautiful set!

What an astonishing set.

My hands would have been trembling while working on such a treasure!

It would be interesting to see a schematic diagram.

Hi Phil,

here are the actual schematics of the set including the changes, I have registered:

http://bs.cyty.com/menschen/e-etzold...Schematics.jpg

Note, that the AL5 spz. and the CY1 spez. are replaced by a 6DQ5 and a 6AF3, until I get the original tubes.

The set will leave my home in the next week :-(

Eckhard,

Beautiful, simply beautiful. What a rarity. Are there any more than maybe 1 or 2 other working examples?

I am in awe of what some of this board can do to bring these old beauties back to life.

That is a fantastic set. Just curious, is in in a museum, or a private collection?

There are IMHO ten surviving FE VIs today, you can find them photographed and listed on

http://fernsehen.bplaced.net/ind_tel.html

I know of another one of them, which is in working condition, you can see it even with a raster here:

http://www.drm-berlin.de/museum/2007/2007.html

The FE VI is the nmost commonly survived prewar set of all German prewar tv sets.

Kind regards,
Eckhard

This is the raster which appears on the screen without an antenna signal. I have got the same raster before I tuned in the channel.

This is an interesting observation Eckhard. Looking at the schematic it appears that the line and frame oscillator stages use blocking oscillators, so I would have expected the set display a normal blank raster. What do you think is causing the displayed raster to look like this when no signal is present?

The height of the synchronisation input level can be controlled by the 5 K control at the cathode of the oscillator tube. My experience is, when I have adjusted the sync level for best synchronisation, and I draw the antenna plug, the raster looks frazzled.

Eckhard,

Really appreciate you sharing this unusal and rare receiver restoration. The set really reflects German prewar attention to detail in design and engineering. I am especially intrigued by the modern looking, metal framed, rectangular control panel (?) above the Telefunken name.

this control panel has only two switches. One switch is for sound (Ton), the other for vision (Bild). You can use this set as a radio, when switching on sound (Ton). When you switch on vision, the vision power supply, the valves of the vision I.F., video demodulator and the deflection units are heated, and the E.H.T. transformer is activated.

Kind regards,
Eckhard

Fully-functioning 70 & 80 year old radios are commonplace on this site....but a working 72-year old television??? Congratulations on excellent work!
