Basic Toy Throttle

The above schematic shows the basic Toy Throttle. It is powered by a 24 Volts AC, Center Tapped transformer to provide PLUS and MINUS voltages. The throttle uses a Push-Pull amplifier that eliminates the need for a reversing relay or switch. When resistor R2 is in the CENTER position the throttles output voltage would be ZERO . Adjusting R2 up or down would produce positive or negative voltage to the track thereby controlling the trains direction. Resistors R1 and R3 limit the maximum output voltage to between PLUS or MINUS 10 Volts.
