Hello everybody,
I changed the Trimmer and all caps on the board of an Beomaster 3000. All works fine... Sound plays in both channels, but I cant adjust the Idle Current on left side. I measure 20mA and it's not adjustable. The other side is not a problem.
What is the reason for this. Can anyone help me?
Thanks very much
Andreas
The resistors close to the trimmer (circuitwise) are known to go high in value.That often causes situations like this.

Hi Martin, thank you for Tip. I measuer this weekend an post you results.
Have a nice weekend
Hi Martin, I measured all resistors arround. They look fine. R 482 has 720 instead of 560. The others are in spec.
Another Idea of this issue? Thanks for help
Replace resistors 480 and 482.
Hi Martin,
replaced and works. Thank you very much. You're great
