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.
Matching of materials and components:
The power tube adopts the brand-new original imported MJ15024 / 15025 audio tube king, 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
Basic parameters
Output power: 20W + 20W
Output impedance: 4 Ω - 8 Ω
Operating voltage; +/-DC30v-45v, that is, the transformer is between Dual AC20-28v, and the recommended voltage is Dual AC26V
Board size: length 210 x width 52 x thickness 25 (mm)
Radiator requirements: the radiator shall not be less than 300 x 80 x 50mm
