This facilitated Push Pull Direct complementary output with the loudspeaker connected to the centre tap. Some makers preferred to use 2 x AD28 for higher capacity centre tapped 9V (e.g. Perdio). Recommended for applications up to 50mA @ 9V
The 4.5V sections each use 1/2 of a PP9 interior and can be used in parallel or series.
