Part 8 Exicon 6: "Blameless" MOSFET Amplifier Project.

The design of Proj8 Exicon6 is inspired by the "Blameless Amplifier" concept. The audio power amplifier is renowned for its low distortion and high fidelity reproduction. Replacing power BJTs with lateral power MOSFETs in the output stage significantly improves thermal stability and linearity —two essential factors for achieving superior performance in audio power amplifier applications. Several changes have been updated to enhance the previous versions of the "Blameless" design. The PCB's top layer has been converted into a ground plane. The output stage is now populated with dual pairs of Exicon's ECX10N20 and ECX10P20 lateral MOSFETs. The driver transistors are complementary TTA004B and TTC004B, specifically designed for audio-frequency applications. The input stage uses the same matched low-noise KSC1845 and KSA992 transistors. The power output is approximately 182.75 watts at 8Ω. THD of 0.0072%, THD+N is 0.00294% and SNR of 91.4dB as measured by the QA400 Audio Analyzer.
