About the VTA-Dyna 70

The VTA-Dyna Stereo 70 is a modern take on the legendary Dynaco ST-70 stereo tube amplifier, designed by Bob Latino. It is a 35 watt per channel vacuum tube power amplifier that offers high fidelity sound reproduction at a reasonable cost. The amplifier uses a patented circuit with outstanding performance characteristics and top-quality parts, including Dynaco Super-Fidelity A-470 transformers. The VTA version features a chassis made of 16 gauge polished stainless steel, which is thicker and more durable than the original, ensuring it will never rust. It maintains the classic power output of 35 watts per channel into 8 ohms, with a frequency response from 10Hz to 40kHz, total harmonic distortion around 1%, and a damping factor of 15. The amplifier uses four EL34 tubes, two 7199 tubes, and one GZ34 tube for rectification. It is suitable for loudspeakers with impedance from 4 to 16 ohms and is ideal for both stereophonic and monophonic use. Dimensions are approximately 13 x 9.5 x 6.5 inches, and it weighs about 32 pounds. The VTA-Dyna Stereo 70 is praised for its excellent sound quality and robust build, making it a favored choice among tube amplifier enthusiasts.
