This circuit transforms 0 and 6 V signals into -4 to 10 V signals and can be used in a shield. The circuit uses transistors that are still common today.
This rather sophisticated circuit does not recognize false tones, such as harmonics, and can be...
This circuit is intended for testing circuits with RIAA equalization. We found this configuration in a 1977...
We found this two stage transistor amplifier circuit using RC coupling in a magazine published in...
