German Prototyp TV
 

This very interesting set was sold on ebay for a remarkable price:

The stamp on the circuit diagram means that the set was not approved for construction.

Thank you Josef for posting. I find it very interesting to see early examples of TVs from Europe. Just don't get to see them very often

Cool set, I can see why it wouldn't be approved, it's insanely dangerous with all that circuitry just a key turn away!
A kid like me would have had that open in no time, Zzzzap!

Interesting set Josef. It appears to be a recreation by someone of a early design. That must have taken a lot of effort!

That's some pretty impressive build construction. Nice and orderly for easy serviceability.

The chassis looks like it might be original. However, with it apparently in working condition, I wonder if its capacitors have been restuffed, or somehow replaced with replicas?

The cabinet looks too clean to be original, although the little number plate and red marking inside looks original, as does the paper tube diagram on the inside wall. Somehow this was kept very clean, perhaps enclosed in a box for most of its life?

Seems odd that it has a vertically mounted pre-war type CRT, but uses post-war miniature tubes :scratch2: The description says it was made in the early 50s.

That's why I was thinking it was a recreation although it does look like the prewar Telefunken FE series and is marked FE 25 so perhaps this was a post war effort by Telefunken using parts they had on hand and newer parts like the miniature tubes?

At first I had similar ideas. So I thought that the set might have mains EHT because of the ununsual construction of the power supply but it hasn't. The CRT is an early 1950s construction as you can see on the spec sheet of this tube:

Never the less the whole mechanical construction is really old school and nice to look at. That was the reason why I have posted this link.

Greetings Josef

I like that!
