This simple diode test appears at other points in this section. Or circuit can be adapted to use LEDs instead of ordinary lamps.
We find this vibrato configuration with transistors in a 1987 documentation. The components are still...
This circuit was obtained in a 1967 Electronics World. The components are still common today, the...
