Class-A integrated vacuum tube amplifier with an output power of 2 x 50 W in PSE configuration. The amplifier can be connected to 4 Ω and 8 Ω nominal impedance speakers. The power outputs, based on output pentodes type KT 120, were tuned to the before-mentioned nominal loads through our in-house manufactured, precision-wound output transformers.
The bias control circuit plays an important role in the operation of the power output too. This circuit monitors the quiescent current of the output tubes and adjusts it to a preset value. Thus, all four output tubes are in perfectly equal operation states.
The KT150 tube can be used in place of the stock KT120.
The balanced input features a mini XLR connector. The clearly arranged, minimalistic remote control was designed in line with the unique and aesthetic exterior design, and the usability was enhanced.
Finally, a couple of words on the set of tubes we use :
The audio signal arriving on the selected input of the amplifier is received by Tungsram ECC83 vacuum tubes. The driving voltage, as well as its matching, are produced by E88CC/6922s.
In the power output stage, the aforementioned KT 120 kink-less tetrodes are in action - strictly in Class-A.
