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.
