Upgraded with DADA kit several years ago and everything works fine.
Looking at the photo on illustrated guide of M12368 board i notice some differences to my board and would like to know if i need to make them.
1. R35 & R36 are linked out (mine are still in place)
2.C3 missing (mine is still in place)
3.D6 in place on photo (mine is missing)
4. D3 & D4 on photo are black and more substantial than mine.
do i need to make these changes?

Thanks

Gary

The wires you see in place of R35 and R36 are the resistors them selves. Quad used resistive wire for those parts. C3 is not neccesary with this type of op-amp. If you are working on this boards replacing D3 and D4 for 1A types is advisible, otherwise don't touch it. They are part of the current limitters and will not come in to action in normal use.
