A question about a Linar 10 amp

Hello

A friend of mine have a Linar 10 amp, it's a five channel amp.

One channel are burn, the output mosfet and the driver transistors need to be replace, but the numbers on the transistors are erased.

Anybody do know wich output mosfet and driver transistors are used in the Linar 10 amp ?

Thank you

Bye
