Here you have a chance to buy rare Sansui board F-6154, Control Amp Board for AU-X711.
It is carefully removed from working unit. As you can see on pictures, I tried to keep all original wiring with connectors. 
On this board you have 2sc3381 and 2sa1349 which are really hard to find today.
Here it is the list of electronic parts what are on this electronic board (taken from service manual)


The board is undamaged, and really in good condition, but selling as untested.
