This circuit is designed based on the imported famous machine circuit.
The chassis adopts a high-end all aluminum chassis, and the knobs are also solid aluminum knobs.
The high-end double-sided thickened gold-plated PCB is designed with dual channels, and the left and right channels are independent.
The 25W advanced sealed ring transformer is used as the UMI beautiful transformer factory with metal shielding sealed transformer.
Ensure the separation between the left and right channels. The two channel ground wires are completely independent, allowing for higher separation between the left and right channels.
The filtering capacitor uses a brand new original Nichicon electrolytic filter, and the audio amplifier uses a brand new American beautiful sound field effect transistor(IRF610/9610) output.
The brand new Taiwan Bennike YONTEX MKP axial coupling capacitor is also used.
The military 718 factory resistor (manufactured by Shenzhou VI) uses relay switching as the volume control method, which can easily adjust the volume (the relay will sound when adjusting the volume, don't mind). Not only does it save the trouble of an external volume board, but it also shortens the signal flow of the music channel and helps improve sound quality. Pure resistance circuit, higher fidelity! N times better than traditional potentiometers! The whole machine operates in a single end Class A state, with delicate and vivid sound quality, round and smooth, rich musical flavor, and extremely high music resolution. The sound is as beautiful as the heavens, extremely durable, surpassing ordinary vacuum tube preamplifiers! It is a very cost-effective preamplifier.
Function: Two relay audio input switching board, which can simultaneously plug in two signal sources and switch between any one.
