This two-transistor delay circuit from the 1960s was found in documentation from the time. Transistors are germanium.
The circuit shown in the figure is suggested by Texas Instruments and allows data transmission on TTL devices...
We find this vibrato configuration with transistors in a 1987 documentation. The components are still...
This circuit, from a documentation from the 1970s, produces two sinusoidal signals given by C2 and...
