| This is the PCB of a power amplifier based on Musical Fidelity MF X-A50. The design features quasi- complementary output structure which is a well proven configuration in Musical Fidelity amplifiers. The board is a compact design with on board rectification and power filtering. Although it is a compact design, it consists of two individual set of driving and output circuitry which is uncommon in normal transistor amplifier. This allows a powerful sound without sacrificing musicality.
Here is the original X-A50 specification for reference :
Output Power：50Wrms （8Ω） , 100Wrms (4Ω)
THD :
Frequency response : +/-0.2dB 20Hz - 20KHz
SNR : >102dB unweighted ; > 114dB 'A' weighted Input voltage : 24Vx2AC to 28Vx2AC C 5A Operating type : Class AB type amplifier. Input Impedance：27K Output Impedance：4-8Ω PCB size：177mm x 76 mm; PCB thickness 1.6mm; 2 ounce thick copper plating. This is a single channel power amplifier. For stereo application two sets are needed.
