tube amp blown fuse symptoms.What can a fuse do?
1. Under normal circumstances, fuses play a connecting role in the circuit. 2. Under abnormal (overload) conditions, the fuse serves as a safety protection component in the circuit, which can safely cut off and protect the circuit through its own fusing. 2、 The working principle of a fuse: When a fuse is energized, the heat converted from electrical energy causes the temperature of the melt to rise. When normal working current or allowable overload current passes through, the heat generated is radiated to the surrounding environment through the melt or shell, and the heat dissipated through convection, conduction, and other means gradually reaches a balance with the heat generated. If the generated heat is greater than the dissipated heat, the excess heat gradually accumulates on the melt, causing the temperature of the melt to rise; When the temperature reaches or exceeds the melting point of the melt, it will cause the melt to melt, fuse, and cut off the current, playing a rol
