Equivalent transistors can be used in this circuit for automotive applications in the 1980s. The frequency is given by the capacitor and the current of the lamp depends on the LM195 transistor.
Powered by 12 or 13.6 V, this transmitter has an output power of the order of 1 W, which provides...
This circuit makes two lamps (or LEDs) blink at a speed that depends on C1 and C2. Any MOSFET can...
This crystal-controlled 1000 kHz oscillator was found in 1980s American documentation. The...
