This circuit was found in a 1967 Delco Radio documentation. The circuit has an input voltage of 250 V and the load current is 2 A. The transistors used are from that time.
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...
