| Keywords: The first headphone tube amplifiers with toroidal audio transformers The most critical part in the tube amplifier is a sound transformer. We use toroidal sound transformers of our own production in the amplifiers. Such transformers are very complex and expensive to manufacture, so nobody uses them, but the sound is ideal. A Mode. There are a lot of modes of operation of amplifiers, such as A, B, AB, C, D... ‘A’ mode stands apart from all others, because only this mode is designed for high sound quality at the expense of power. The rest of the modes operate to get maximum power at the expense of sound quality. Short section. In circuit design, we adhere to the principle of a short section, because each additional stage adds distortion to the sound, it can be compared with the window frame with more than one or two panes, but with 10 or 20 ones. Each amplification stage turns out to be such pane. Only a short section can provide high-quality sound. Triodes. Boost Stage is assembled on a double triode 6n8s (analogue 6SN7). We only use triodes, because they have the lowest internal resistance, which has a positive effect on the quality of sound. Components. - Boost Stage: Wima and Vishay capacitors. Vishay resistors - Power Stage: Capacitors Cornell Dubilier Electronics (CDE), toroidal power transformer Reliability. All the details of the circuit are selected in such a way that the amplifier has worked for decades with no repair and maintenance. We do not use printed circuit boards, because microcracks eventually appear on them. Amplifier circuits are assembled by point-to-point wiring. Point-to-point wiring is for ever. Housing materials - wood and steel. We do not have mass production of amplifiers, each device is assembled and adjusted according to the individual. toraudio.com tubeamplifier headphoneamplifier headphonetubeamplifier tube sound audiophile hiend | ||||
