Winding the audio transformer of tube amplifier with multi-slot skeleton: The quality of tube amplifier power amplifier is closely related to the performance of audio transformer. High-performance audio transformer is complex in design and difficult to wind, which is much more complicated than power transformer, because power transformer works at a single frequency, while audio transformer works in the audio range of 10Hz~100kHz or even wider. Therefore, on the one hand, it requires a larger inductance to obtain a good low-frequency response, and on the other hand, it requires leakage inductance and distributed capacitance to be as small as possible to obtain a good high-frequency response, and inductance, leakage inductance and distributed capacitance are increased or decreased synchronously. In order to solve this contradiction, it is necessary to adopt layered and segmented cross-clamp winding and other methods to reduce leakage inductance and distributed capacitance. When winding, a thin layer of cable paper is placed between the layers to further reduce the distributed capacitance. To use this method to wind, you must have certain experience and skills, be patient and meticulous, not afraid of trouble, and flatten the outlet end to avoid occupying more windows so that the coil cannot be wound and it is futile. At the same time, the number of turns of each layer and each section should be recorded in time, and each beginning and end should be marked for identification. It takes a lot of energy and time to go around from the inside to the outside layer by layer.
