Hello,
yesterday, I have picked up the Kuba Porta-color. It is in good condition, much better than other ones, I have seen. The emission of the 11SP22 is 0.4 mA on Blue, 0.38 mA on Green, and 0.38 mA on Red. This seems to be low, but keeping in mind that only a small screen has to be illuminated, this might be enough. What's your opinion?
The set is operated with a rainbow colour test generator and with Darryl Hock's World converter. In the rainbow, the red bar is missing. Green is yellow, and Cyan tends to purple. The burst signal, which is extracted from the chroma signal, is faulty. Where I should have only a small peak with the burst, I got a sawtooth signal.
Kind regards,
Eckhard
