The speaker must be connected before starting work, the bile machine must not be idle, otherwise the transformer will be burned.
This machine circuit features
・It can be used for CD/DVD and vinyl record player (RIAA).
・The amplifier has high/low two-level output (0.7V/0.2V), which can be adapted to pure post-stage amplifiers and combined amplifiers.
・The vinyl disc phono amplifier adopts the female-female feedback type equalization circuit, which conforms to the RAA characteristics and has a good sound.
・The pre-amplifier is a cathode output circuit, which has the advantage of low impedance transmission.
・Signal conversion adopts light-touch relay conversion to ensure high fidelity. 12AX7B and 12AU7 are used for amplification, and the vacuum tube filament is DC power supply to minimize the noise of the machine.
・This machine is manufactured using imported audio (MKP) cross-connecting capacitors, imported audio filter electrolysis and high-precision gold resistors.
・The power transformer is made of oxygen-free copper enameled wire and imported audio (0.35MM thick) silicon steel sheet and special winding process..
