This inverter is critical for transformers and can use modern equivalent transistors like MJ2955 on the output. The circuit provides a 115 V sinusoidal voltage with 12 V input.
This crystal configuration can be made with triggers of any logic. The frequency is given by the...
Only two transistors are used in this preamp for low-sensitive transducers, such as guitar and...
This project from a 1983 publication can be assembled using more modern transistors. We can use...
