Found in an Electronic Design of 1964, this circuit can control up to 20 SCRs in a trigger system powered by 24 V. The SCR supports a modern equivalent.
This circuit is from an old manual, but can be easily assembled as the integrated one is still...
The simple transistor test shown in the figure can be powered by a 9V battery. The test is for...
This regulator can use BD'136 as the main transistor and as a reference next to a BC548 zener. The...
