Look at the transistor markings on the PCB. Two have a tiny arrow pointing inwards. These are the BC557. They are at the end of the board with the unicorn. One is near the unicorn, and the other is about 1/2" diagonally away from it.
All the rest have the little arrow pointing outwards and are BC547.
You cannot use all BC547.
