    Pretty sure that's the AM modulator transistors. Yeah, it 'regulates' the AM carrier as well. It's a NPN transistor, and there are a lot of them that will do the job.

    We have used 2SD613, MJE3055T, TIP41A, B or C. Don't know the number used in that generation of 148GTL radio. There are literally dozens of generic NPN power transistors that will work.
