Yes, all these findings are quite regular for a discrete transistor power amplifier.So for each of the circuit, there's two different transistors. When looking at them dead on (with a given circuit), the transistor on the left is a MN2488 55P, and the transistor on the right is a MP1620 55P.
And yes, they each have three prongs.
