The radio is built around the IC KA22426, containing all the active circuitry for a radio, including a 400mW output amp. The AM IF is 455kHz, as witnessed by the U455B ceramic filter. For FM, the IC contains a quadrature detector. The S9018 transistor can be used as an AM pre-amplifier, so my guess is that this is its function in this radio. The 9014 is on a separate circuit board and its purpose is unclear to me.

When you open the set, you first see the upper side of the PCB, and the radio IC only becomes visible when you take out the chassis. The soldering isn't very neat, so I think it has been repaired at some time.
