Found in a 1965 Electronic Design, this circuit divides the frequency of a cascaded signal using unijunction transistors. The bipolar transistor supports an equivalent. The shock is 470 mH.
This common configuration is one of many that can be found in this section using the 555. The...
The load on this amplifier is 8-ohm. We found the circuit in a 1972 Motorola amplifier manual. The...
