The VS70 stereo balanced power amplifier adopts the same balanced design as the VM60, mainly using lower power vacuum tubes and output transformers. The balanced working mode can effectively eliminate electromagnetic noise absorbed from the signal line, and it has a patented dual balanced feedback topology (DBFT) circuit. The product features include fully balanced input and output, stereo design, high-quality C-core choke coil and electrolytic capacitors in the power supply, and high-quality silicon steel sheets in the output transformer.
The VS70 is a stereo vacuum‑tube power amplifier that uses a Dual Balanced Feedback Topology (DBFT) to improve linearity and sound quality. It features a fully balanced input and output stage with high‑quality tubes that have been pre‑aged for optimal performance.
The manual provides product features, detailed specifications such as output power, frequency response, and input/output characteristics, as well as wiring diagrams and setup guidance for both RCA and XLR connections. This manual is written in Chinese.
