Congratulations
Thank you for choosing Tube Driver BLUE. This latest
USA-
patented
creation of BK Butler, promises to become a classic just
as his former Tube Driver designs have. With careful attention
given to the attainment of "all tube" response characteristics in a
mobile environment, Tube Driver BLUE will satisfy even the most
critical audiophile. For the first time in the history of tube amplifier
design, the original "Edison effect" has been fully utilized to
achieve low THD distortion in an
open-ended,
high-powered
vacuum tube hybrid amplifier. By carefully balancing the sonic
response, load and transfer characteristics of carefully selected
triode vacuum tube drivers, BK has achieved astounding results.
Tube Driver BLUE uses
ZERO
global negative feed back which
results in greatly improved sound quality with an extremely warm,
open and transparent qualities. The design is truly original and
sets a new musical standard for mobile audio.
As essential as clean power is for good sound reproduction,
natural
DYNAMICS
are equally important. Tube Driver BLUE
produces unmatched musical dynamics and the 'punch' of a live
concert performance. High current bipolar output sections are
servo-driven by dual vacuum tube triodes, which directly reflect
the speaker load. This results in authentic high-performance
power tube response characteristics of "all tube" designs.
Best of all, this natural vacuum tube response is created without
traditional large and heavy output transformers or dangerously
high power supply voltages. Tube Driver BLUE sets the new
standard for musical vacuum tube reproduction and rivals even
the most expensive home audio vacuum tube equipment.
