      Bad left channel- so I switched the two RCA HN 7748 and the problem moved to the right channel.
      But I can’t find these RCA on the internet or what I can use instead. It is the two green ones, on the board IC101 and IC102.

      Anyone who can help?beomaster1500-1

        Those were power darlington transistors. You can use BDX33A and BDX34A to replace them.
