60
The Balanced Audio Technology VK-60 embodies the elegant application
of modern design principles to vacuum-tube technology. It incorporates all-triode
zero-feedback topology, fully balanced operation, the ability to drive difficult
loads, and true automatic biasing. The result is a power amplifier that is both easy
to use and musically without peer.

Musical clarity
The VK-60 offers the startlingly lifelike midrange of the best single-ended
amplifiers while delivering the dynamic power and frequency extension associated
with push-pull models. Its single-ended bridge design avoids the direct current
that compromises output transformer performance in single-ended amplifiers and
eliminates the crossover distortions inherent in push-pull designs. Without
these debilitating artifacts, the VK-60 opens a magical window on the original
performance—a direct emotional connection to the music.
Commanding authority
Dynamic or hybrid speaker systems often require substantial current to achieve
optimal performance. The VK-60’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. The VK-60’s innovative design exploits
these strengths to drive real-world speakers with commanding authority.
Automatic bias
The VK-60 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
warmup, aging, and variation of tubes as well as fluctuations in line voltage. Just
turn the VK-60 on and enjoy the music.
Versatile performance
The VK-60 is available as either a 60-watt-per-channel stereo amplifier or a
120-watt-per-channel monoblock. The owner of a stereo VK-60 who acquires less
efficient speakers or a larger listening room—or simply wants more power—can
add a VK-60 monoblock and have the original unit easily updated to monoblock
format. In either configuration, the VK-60 delivers reference-quality performance.
We invite you to consult the VK-60 white paper. Then visit your BAT audio
specialist to hear music as you’ve never heard it before.
