Could any expert kindly suggest some commonly available transistors in place of the above mentioned?The author's E-mail: [email protected] for questions - info. seem to be no longer available.

audioguru Posted February 12, 2007 Report Share Posted February 12, 2007 Hi Chub,It is not a 200W amplifier. Its text says it produces only 120W into 4 ohms. It does not mention how much distortion. If it produces 120W into 4 ohms then its output would be only about 70W into 8 ohms.It is an old circuit that uses hard to find parts. Why not make a modern circuit that actually produces 200W?This site has some modern 200W amplifier circuits:http://www.ampslab.com/projects.htm Quote Link to comment Share on other sites More sharing options...
