The most wanted German E1 was sold

That is one cool tv. I was looking at the map for it and didn't see a cap over 30 uf.
Not even in the power supply. Do any of you guys see any?? What awesome electronics

The E1 has a low power consumption. See the vertical and horizontal output tubes, the anode resistors are 2M and 200 K while the screen grid is connected to the transformer and the yoke directly.
Here are the schematics in a large picture format:

Total power consumption was 185 watts.

Someone skillful in cabinet building could, with the use of a small portable B&W TV set, build an operating reproduction. Of course the internal guts would look all wrong... Next level is to build a technological equivalent with similar tubes and circuits.

Meanwhile the E1 is fixed and restaurated. When it was sold, it was in so bad condition that it was not operable. The main elko had a short and would burn the main transformer if it wasn't replaced. The condenser coil for the electron beam of the crt was broken, and some other more failures. Now it is working again, with original 441 lines video. Here are some photos of the restaurated and clean set:

Today I have got a photo with the E1 working. The input was a sine wave signal. This greenish white of the phosphor is original and not a tint of the camera.
In the next weeks I will get more photos of the E1 driven by an original video signal from a standard converter.

What a beautiful piece of history. I would love to have one, but I can understand the owner wanting to keep it in the country of origin.

It is the last remaining set of this model in operational condition. The screenshot demonstrates that the CRT has full beam current and is able to focus it correctly.
But as far as I know the owner and set will move to Switzerland. Such is life!
But before he will move, I will visit him. I will never be able to own such a rare and valuable set, but I only want to see the E1 working with an original video content of that time in my life. (And all the photos I will take, I will report here on AK!)
