This transistorized circuit is powered by a voltage of 6 to 12 V providing high voltage for a neon lamp. The circuit is from a 90's publication. Modern equivalent transistors can be used.
Suggested by General Electric in a 1965 document, this circuit can accept a greater number of...
This circuit is from a 1970 publication, having been implemented with germanium PNP transistors. We can...
Many oscilloscopes have high impedance inputs that make it difficult to observe high frequency signals...
