SORRY FOR PROBLEM

Here is Chucky Locator

 
Ich hatte auch das 10K/1Ohm Problem und noch was. Ich hatte massive Probleme mit dem Sound. Ich konnte die Filterfunktion dafür verantwortlich machen. Bestückungsfehler R435 und R445 sollen 470K sein. Bei mit waren 4R70 verbaut. Das sind nur 4,7Ohm!
Getauscht und jetzt läuft es wie es soll.

I also had the 10K/1Ohm problem and something else. I had massive problems with the sound. I could blame the filter function for this. Assembly errors R435 and R445 should be 470K. 4R70 were installed. That's only 4.7 ohms! Replaced it and now it works as it should.
 
Well, manufacturing company should have at least a basic optical testing system to sort-out such mistakes. That's why it is better to solder manually :).
