Hi!
I am currently trying to give a new life to a nice little Sony KV-4SV2. The service manual is freely available here

The first thing I did is clean the boards and replace the high temp capacitors that were leaking (all of them).
I then realized that the previous owner might have done repair as it appear some parts on the D1 board are missing. Obviously Q1501 is not there. The same for other SMD components next to it. See picture.
I cannot determine what is missing based on the service manual and the annotations on the PCB have been damaged by the cap leak. Any one has picture of the board or any info that could help ?
Many thanks
