I have a problem with the amplifier 9bst, I have broken two channels and I can not find the component.
these components are br6521 and br6522, I can not find the datasheet and equivalent.

Those are relabeled transistors.

Use the search function with "br6521" and/or "br6522" and you'll be able to find at least four threads in this forum where replacements are mentioned.

good morning
I already tried with the search in fact there are already discussions about it.
I already tried to replace the components with the MJE MJE 15031 and 15030 but I jump 2 22ohm resistors R26 and R83 precisely changing the sound source.
