Earth Sound Research Parts

Hello,
I have a module 340 P.A. mixer amp that has blown the output transistors. They are marked
S 59-4004-B. Does anyone know where I can find replacements, or a better modern counterpart? These are the only parts needed to get this thing going again, so any help is appreciated.

Thank you.
