VK-90 uses eight 6H30 SuperTubes to form an extraordinarily high-current, low impedance drive engine. VK-90’s signal is effectively transmitted through only one gain stage. The Unistage™ circuit provides the ultimate simplicity of amplifying the incoming signal only once, while using no global feedback to double back on the straight-through signal integrity.
