X-A50 50W Quasi complementary power amplifier PCB 2 pieces

Here are 2 pieces of PCB of a power amplifier based on Musical Fidelity MF X-A50. The original amplifier is a monoblock design so here we offer two pieces of PCBs as to form a stereo application. 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. The design even includes current limiting circuitry to protect the output transistors from failure.

Sound Performance

"... turned out to be lively and cheerful. Is it due to the use of a tube cascade in the pre-amp or not, the amplifier's sound was airy and stunningly detailed. "
