VT-20 BSI

KR Audio VT20 Tube Amplifier. This product has passed all of our rigorous quality assurance testing and is performing wonderfully. This amp is about 5 years old; 2 owner; both non-smokers; No known service history. Serial #: 526 Voltage: 115v Very special amplifier from KR Audio. The designer Dr. Kron has combined the tube and transistor technology into one piece. The result is a tube, which is in real vaccuum and contains one transistor. Thet VT20 uses two of those tubes, one for each channel in single ended mode with zero negative feedback, just like the set amplifiers. The goal of this technical black sheep was to combine the benefits of both worlds and loose the disadvantages of both worlds. This amp delivers 50 watts of single ended pure class a each channel
