Classe audio ca-150 power amp swap output transistors to MJL21194G from 2SC4029 good or bad ide ?

[bonesbiggis]

I have found some burned 2SC4029 and 2SA1553 output transistors. I also found some new MJL transistors laying around.

Is it god idea to swap to MJL21194G and MJL21193G ??

What different dose it make to the sound and funktion off the amp ?

In the manual is it MJL transistors. Why is the amp fitted with 2SC4029 / 2SA1553 ?

Well, what are the specifications of said transistors? Transistor datasheets will be more useful here than the service manual.

MJL21194G / MJL21193G = 16A 250V 200W
2SC4029 / 2SA1553 = 15A 230V 150W
