THE VK-75 AND VK-150 MAKE A POWERFUL STATEMENT,
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.

Specifications
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.
