The Absolute Sound Tube Amplifier

Acuhorn TT original tube amplifier, if you want to experience the sound of one huge tube. A supply power with ultra state of the art DC-DC converters working at mega speed. The idea origins are like in the first amplifiers Western Electric. The amplifier is classical output transformer and applies grid input transformers similar to UTC LS-10. Here is only one serviceable element, the single ended SE 6C33C triode, to be exchanged.

the sound of one huge tube 6C33C without small driver tube. One tube amplifier type with input and output transformer. Self-biasing amplifier without adjustment of the tubes. Only one 6c33c tube is serviceable part to be exchanged. Design amplifier the highest level of Amperes work in class-A. Plate current 400 mA 3000 h reliability. Plate dissipation 60W. Plate voltage 200V. Internal resistance RP 80. Warm-up time to 90% emission 120 s.

Line to grid transformer similar to the UTC LS-10. Designed for multiple input sensitivity. Direct input to the grid with preamplifier. For 600 ohm sources at input sensitivity 6V. For 50 ohm sources at input sensitivity 2V. Optional four sections input transformer for match volume control. Absolutely minimalist audio path. High quality precision 0.1% thin film Nichrome chip resistors. The amplifier has a mono mode switch. For mono connect the speakers to the output in series or parallel.

Power supply is the best Vicorpower modules. DC-DC converters provide high power density and low noise High frequency Mhz switching. Advanced power processing in a small size. Autoranging 90-264Vac network voltage, for worldwide use.
