Ed:
the Faehnrich was a very cheap set. All what is not absolutely necessary was omitted. Therefore I estimate it not as complex. The Philips color tv sets are much more complex, Saba also.
The Graetz color tv sets of the generations before had two line output transformers, one for high voltage with a regulator circuit (no shunt regulator) and one for the horizontal deflection.
The line output unit of the Faehnrich is designed like the b/w horizontal output units. In my opinion it is very similar to the GE portacolor. Perhaps a shunt regulator might not be necessary because the beam currents are lower then in the sets before. The CRT measured not good, but useable. But the phosphors seem to be very efficient. The good picture might not depend on high beam currents but on effective phosphors.
A wired remote control can be connected. No ultrasonic remote.
In the moment I have no time to work on the Philips K7. Xmas is coming and I have to prepare the Xmas services and a lot of presents for the family. Perhaps I found some time around midnight to make the measures at the luminance controls.
