For sale, my Balanced Audio Technology (BAT) VK-55 mono
blocks. I am the second owner and they
have performed flawlessly since day one and sound amazing. I purchased them from Scott Walker Audio,
California’s premium high end audio dealer.
I have meticulously cared for them and am
rating then 8 of 10 because of their age.
The tubes are new and have less than 40 hours on them. Included are the jumper cables to convert
them to mono blocks.
The Balanced Audio Technology VK-55 represents the
meticulous application of modern design principles to the development of a compact
and supremely easy-to-use vacuum-tube power amplifier that sets a new standard
for musicality in its class. The result is a unique combination of fully
balanced, all-triode design topology and automatic biasing of individual output
The VK-55 uses the same high-current dual-triode 6C33C-B
tube employed in their flagship REX II Power amplifier. The VK-55 (55Wpc stereo, 110Wpc mono block
configuration) delivers the high-current kick required to drive even difficult
low-impedance speaker loads.
The power amplifier’s advanced engineering eliminates the
traditional headache associated with most vacuum-tube power
amplifiers—specifically, the constant need to set and readjust the proper bias
of the output tubes—as the VK-55 features an intelligent automatic bias
design that adjusts for changing line voltage and aging tubes, with each output
tube having its own dedicated bias circuit.
