? D666AC, B646AC -vs-C2705 ,A1145 - which one substitute which one?

I got schematic that using the following transistors: D666AC, B646AC. However, a vendor gave me C2705 and A1145 instead.

I wonder if which one is the substitution of which one?

:confused: :confused: :confused:

2Sc2705 is NPN as 2SD666AC.... so, they may be equivalent

And the others may be PNP and equivalents too.

Good luck

Yes, but that girl is the amp construction supervisor or assembly assistant, and the pictures of food are the energy source required to build amps at the Carlos's hectic pace. ;)
