When an alternator is used to supply constant current, it needs an adjustment that must be made as shown in the figure. The potentiometers are of low wire value with high dissipation.
We found this relaxation oscillator in a 1967 General Electric documentation. The frequency is given...
This circuit was found in the September 1984 issue of Radio Electronics magazine. The circuit has...
Although the BD135 transistor is not specifically for RF applications, some of them can easily...
