This Preamp adopts the design of 4 inputs and two outputs, and the 2 outputs could be output to 2 totally different energy amplifiers or lively audio system on the similar time. All use pure copper gold-plated ports.
The facility provide adopts two impartial El sq. transformers, excessive voltage and low voltage separate output design, and the sealed protect is fastened within the chassis to reduce energy interference.
6N4 and WY1 are used to type a multi-channel parallel voltage-stabilized energy provide system after the 6Z4 tube is rectified. The tube screens of various working states are respectively provided, and the impartial energy provide and the opposite tubes aren’t interfered with one another.
The filter capacitors of the entire Preamp are all coupled with imported polypropylene capacitors with good repute.
Excessive-performance parallel energy provide voltage stabilization half with 8532W electron tube for voltage amplification
Mixed with low inner resistance J-level 6J9 as cathode follower output, it makes the Preamp’s technical indicators first-class, the distortion is as little as solely 0.018%, and it has wealthy ninth harmonic parts.
Imported Teflon silver-plated wire is used to enhance sign particulars, cut back loss and cut back noise.
The MCU change is used to regulate the absolutely sealed relay to realize sign conversion, avoiding switching noise and lengthy life.
The sign output makes use of a relay delay to keep away from the noise generated by the digital tube in the course of the preheating course of. Built-in sound path choice LED indication on the panel.
