The integrated circuit and configuration are uncommon. However, the sound quality is good. The circuit is from the 1983 Intersil Databook. The output transistors must be provided with heat sinks.
The circuit we have just described has been mounted in the car of the author of the project for...
This circuit was found in an old European publication, but it can be implemented with more modern...
This circuit is based on a PLL 566 and generates positive ramps. The frequency depends on Rx and C...
