Hi Radek,
Seems that the KLM-367 is not the issue. BTW the intensity voltage should
vary from 5V (0) to +5v (10). Next turn to the KLM-368 and check the switch
input buffer op-amps (IC23) and then the quad bilateral switch IC14. One
thing to note. I have had various NE571 compander chips fail on these board
before which cause numerous and amusing effects of there own!
Let us know how you get on.
Cheers,
Andy
