70W Class AB Hi-Fi Amplifier
This project considers the development of a 70W Hi-Fi Power Amplifier for use as part of a Hi-Fi separates music system. The design is a fairly simple circuit topology, which is easy to understand and the author believes that the finished result sounds very nice indeed. The web posting is developed from an original design document available in pdf below. The detailed design issues are discussed in the pdf, while this posting discusses the more practical issues involved in producing the amp.

Build your own LC Meter and start making your own coils and inductors. This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils. LC Meter can measure inductances starting from 10nH - 1000nH, 1uH - 1000uH, 1mH - 100mH and capacitances from 0.1pF up to 900nF. The circuit includes an auto ranging and "Zero Out" function to make sure the readings are as accurate as possible ... [more] |
