This is my project for home use. Complementary mosfet amplifier 300w(8R). PSU-Unit for audio with very fast power response and low IMD conduction on amplifier. Regards P.S. Amplifier is free(not Reserved), I can post on thread complete schematic. Include low-noise,flat response, CD player preamplifier on board. Last edited by AP2; 21st March 2010 at 11:29 AM. |

Hi,
I can now proceed to listen (I have two mono-block), 2x speakers are Sonus Faber "Amator". I first checked all the protections included dc-offset.  Short put on this thread all measures. Jazz and classic I think is hard test with this speakers. PSU out +/-70V Regards |

Hi PMA,
This is Class A-B MosPower amplifier. we're listening to a real surprise to the growing behavior (classic music), and string bass (Jazz). it is obvious that the PSU voltage drops very little. Ok, after listening to continues with measurements Regards |
