DESCRIPTION

The performance of any preamplifier, tube or solid-state, is going to be determined to a large degree by the amplification device used. The advanced design of the Balanced Audio Technology's VK-50 balanced vacuum tube preamplifier gets maximum available performance out of the industry-standard and highly respected 6922 vacuum tube. Developing a preamplifier capable of performance superceding that of the VK-50 would, therefore, require a new amplification device with performance characteristics unobtainable from the current supply of existing vacuum tubes. Our search led us to discover a unique tube totally unknown to the West, produced exclusively for use by the Soviet military. Until the summer of 1998 this tube was banned for any export. As soon as this ban was lifted, Balanced Audio Technology obtained the exclusive rights to this new device.
