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.
