Hi,
some weeks ago, I got a surprising telephone call. I was asked to restore a German Telefunken mirror-lid prewar tv set from 1937, and to bring it into working condition. I was unsure whether I have the skills to do such a thing. I was afraid about the handling of the prewar picture tube. But nevertheless, I said yes. Two weeks ago, I got the set, and is in good condition. Unfortunately, the E.H.T. connector at the picture tube is broken (see photo). The picture tube itself is still under vacuum and has still silver getters. The filaments are also OK.
The set was upgraded to 625 lines in the 1950s. I have rebuild it back to 441 lines television standard.
The original line output tube, an AL5 special, is missing and hard to find. It was replaced by a 6DQ5. I hope that I can get an original AL5 special tube with the plate cap.
With the help of Darryl's World Converter, I could operate the set. Here are some pictures and a video:
