Amplifier With pefect protection circuit to Protecting your expensive speakers.
Musical Fidelity A1 is a very classic circuit. Whether it is human voice, high frequency or low frequency, it has very good expressiveness.
This board adopts the original circuit of A1 without any change. With my more than ten years of drawing experience, this circuit has a very high signal-to-noise ratio and replica. This board is more suitable for DIY assembly, and I think the layout and rationality of this circuit are no less than the original.
On amp board. The power TRANSISTORs adopts the brand-new original imported MJ15024 / 15025, and the push transistors adopts ON ml340 / 350 resistance. Taiwan kunmao coarse copper pin 1% high-precision resistance. In order to fully express the voice of Britain, all capacitors adopt Elna natural silk film capacitor, which makes the sound softer.

Original Japan ALPS RK27 volume potentiometer.
300W Oxygen free copper Toroid transformer.
Pure copper frosted RCA sockets and output terminals.
Full aluminum chassis+stainless steel switch.
