BEOMASTER 1500 found the prb. but need help.

Bad left channel- so I switched the two RCA HN 7748 and the problem moved to the right channel.
But I can’t find these RCA on the internet or what I can use instead. It is the two green ones, on the board IC101 and IC102.

Anyone who can help?

Those were power darlington transistors. You can use BDX33A and BDX34A to replace them.
