VK-90T

About the VK-90T

The Balanced Audio Technology VK-90t is a high-end, fully balanced stereo tube power amplifier that can also be configured as a monoblock. Its symmetrical single-ended bridge topology uses an all-triode signal path, no global negative feedback, active current sources, and a high-current output stage. Features include intelligent automatic bias with LED indicators, fuse-less protection, a 25th-anniversary aluminum chassis, silver-gold oil capacitors, and upgraded internal signal wiring. The amplifier is designed for demanding loudspeakers and may be converted from stereo to mono operation. Current manufacturer and dealer listings indicate that the VK-90t remains a listed product, although some third-party listings describe examples as discontinued or closeout stock; therefore, its exact production status may vary by market and inventory.
