This circuit was found in Motorola's 1967 documentation. The circuit makes use of power transistors of the time. For pulse pickup an appropriate pickup coil is used.
This high input impedance circuit makes use of two operational ones that are still common. The...
This circuit is suggested by Motorola and consists of a voltage reference based on an MC1403. The...
The output voltage is adjusted by the trimpot. The power transistor mist be mounted on a heatsink. The 3.9...
