The FV-2020 machine is an improved and upgraded version based on the F1 pre-amplifier circuit from my store. Originally, this machine had several thousand sales in my store, with high user satisfaction. Now, it has been redesigned and produced according to the aesthetic tastes of modern users. Based on the original machine, the layout and materials have been changed, with two channels independently powered and amplified to minimize mutual crosstalk effects. This ensures purer sound and more accurate reproduction. The machine is powered by a Class A power supply, which can fully exhibit the warm tone of the original design.
The standard configuration of this machine includes four operational amplifiers (two operational amplifiers are used for amplification in each channel)
