Hi,
I have a lot of these transistors and want to use them for repairing my ASW-4000 amplifier from B&W.Originally is placed 2SC5200 and 2SA1943.
Can they be just swapped if i also replace drivers for them?

I suggest to investigate from the very start of the circuit, if there are low signal transistors, resistors and diodes, damaged. Usually those transistors, when blow, kick back trough its base connection, making a cascade of components burned although its appearance is OK.

Yes they can be swapped for the 5200/1943's, but as Osvaldo mentions - make sure the rest of the circuit is working properly, or you will just have more blown transistors.
