DONIZETTI anniversary commemorative
Power amplifier Donizetti''''''''s anniversary, newly born audio simulation, designed in the air technology laboratory, is part of the anniversary line, and re -proposed the audio simulation of another historical product. This new model and the previous version of Donizetti are still the name, and the technical solutions used by projects and used are brand new. This is a high -power stereo power amplifier: its 250 W@8Ω double impedance can drive any speakers late. The amplifier has a complete dual single configuration, from two 1200 units 1200 The VA ring transformer starts, designed for low -decentralized flow. Use our Segesta (single -increasing cross -guide amplifier) ??configuration, and then provide all the necessary currents with a set of four crystal tubes without affecting the gain level. The amplifier does not use global feedback. The four -layer printing circuit is designed to make the input signal never intersect with the output signal, so that the sensitive amplification level is as far away from the power transformer as much as possible. All components are high levels. Starting from the standard resistance of the monarch, continue to use the AIRTECH -specified capacitors until the 7n OCC copper wiring, then to pure copper and gold -plated connector. There are two versions of silver and black anniversary.
