The extended use of a high powered audio system may
result in hearing loss or damage. While TUBE DRIVER
systems are capable of
"Concert Level"
volumes with
incredible accuracy, they are also designed for you to
enjoy at more reasonable levels all of the sonic subtleties
created by musicians. Please observe all local sound
ordinances.
Thank you for choosing TUBE DRIVER. Tube Drivers musicality and absolute sonic
transparency allow accurate reproduction of recorded music enabling you to hear as well as
feel the music the way the artist intended. These handcrafted amplifiers feature full differential
“front ends” based upon a true instrumentation amplifier topology. Tube Drivers utilize only
the highest quality Svetlana tubes in our unique configurations. All of the internal amplifier
stages have been designed to have ultra-wide bandwidth together with a high degree of
linearity. The tubes used in these amplifiers provide both voltage gain and current gain where
they are connected in Cascode and Cathode Follower configurations. D.C. servos are used
to control any D.C. offset. These servos are critically positioned in the circuit so that not only
is D.C. offset eliminated but also any subtle differences between tubes are internally
compensated. These tube stages are then connected to a high current BiPolar output stage
that uses the same audiophile quality Sanken output devices featured in the PrecisionPower
2500F1.The output stages receive their power from a highly regulated D.C. power supply
which enhances their performance significantly. Very little negative feedback is used. Low
feedback designs have greatly improved sound quality having an extremely warm and open
sound with enhanced musicality consistent with only the highest quality home tube amplifiers.
