This circuit is temperature stabilized. Modern equivalent transistors can be used, and the power supply can actually be between 9 and 12 V. The circuit is from an old documentation.
The purpose of the practical circuit shown in the figure is to generate a pulse of programmed...
The LM1468L can also be used. The circuit is from Motorola's Linear Interface ICs and the...
We found this circuit in the January 1970 issue of Radio Electronics magazine. The transistors are general...
