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.
We found this power supply in the 1982 SGS Linear Integrated Circuits manual. The L296 is not...
This circuit is from an English book from the 1980s. Transistors can be general-purpose types of...
The basis of this circuit is the integrated TA7205, which is not very common today. We found the...
