    Thank you very much Filip.

    I was almost sure about that, but just  – ‘livrem og seler’😊

    I might replace the trimpots after alignment. Out – find how many Ohms, and probably make two fixed resistors i parallel do the same. In a Beomaster 9000 I have seen a similar trimpotentiometer perform erratic after af few decades, resulting in a pretty hot output stage.

    Hi Filip

    I saw that you aligned idle current between 2TP200 – 2TP201  for 11 mV  , and similar for the other channel.

    I suppose that is across both emitter resistors 0,22ohm?

    Cannot find these TP stipulated on diagram or print.
