The VK-75 & VK-150

1X Views 3X Views

The Balanced Audio Technology VK-75 brings new power and performance to the most advanced vacuum-tube amplifier architecture on the market. Like its predecessor, the classic VK-60, it incorporates all-triode zero-feedback topology, fully balanced operation, the ability to drive difficult loads, and true automatic biasing. Combine this heritage with greater power and a refined circuit design, and the result is an amplifier that reproduces music with sheer artistry.

MUSICAL ARTISTRY

The VK-75 offers the startlingly lifelike midrange of the best single-ended amplifiers while delivering the punch and frequency extension associated with push-pull models. Its single-ended bridge design gives the VK-75 the sound BAT amplifiers are famous for: open, free-breathing, delicate, and with effortless dynamic responsiveness. The VK-75 captures spatial information superbly, and places properly scaled, fully rounded instrumental images on a panoramic soundstage.

COMMANDING AUTHORITY

Dynamic or hybrid speaker systems often require substantial current to achieve optimal performance. The VK-75 s 6C33C-B power tube is unique in its ability to deliver high current at a relatively low plate voltage several times more current than the popular 6550 power tube. It vastly simplifies the output transformer s task of transferring power to demanding loads. With a completely re-engineered power supply providing 75 watts per channel into 8 ohms, the VK-75 drives real-world speakers with commanding authority.

AUTOMATIC BIAS

The VK-75 eliminates the traditional headache of tube power amplifier ownership the constant need to adjust the bias of the output tubes. It features a sophisticated automatic circuit that performs real-time bias control of each individual output tube. Without sonic penalty, the automatic bias circuit compensates for the warm-up, aging, and variation of tubes as well as fluctuations in line voltage. Just turn the VK-75 on and enjoy the music.

THE VK-150 MONOBLOCK

The monoblock version of the VK-75, the VK-150 supplies a prodigious 150 watts of output power. The stereo VK-75 can be fully upgraded to VK-150 monoblock status, maintaining the commitment to a rational upgrade path that has won BAT unprecedented customer loyalty. In addition, both stereo and monoblock versions can be upgraded to BAT s signature VK-75SE and VK-150SE editions, which incorporate the unequaled Russian 6H30 SuperTube in the driver stage. In any configuration, BAT tube amplification delivers world-class performance.
