BD241 and TIP42C are not darlingtons even BD241 is NPN so they are not suitable but bdw94c , tip127 , tip107 ,tip137 seems to be OK for substitution.

Regards!

This class H can't work with 5 pairs of outputs, but is ok for single pair like in H200 (post #88)

Fan control can't work with amp input, use unregulated 15-18vdc for suply.
