I need a little help because my KSW-10 does not start.
The led remain red. I have already checked the signal from the speakers and it is OK.
I did not change the wiring and in the last weeks I saw he had some problems (a delay) to start.
I checked also the board inside (I am practical in electronics) and i found a couple of dirty solderings near two power transistor (probably the series regulator for power supply) but the problem is not there...
So, maybe other users had the same problem and also the schematic diagram can help me.
Thank you in advance for your answers.
