Precision Power TD450 specifications R Y O U R R E C O R D S

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.
