The 6amps. Fuse Keep on cutting after replacement

The 6-amp fuse in the Ahuja UTR-30E may keep blowing due to several possible reasons:
1. Short Circuit – A short circuit in the internal components, such as the transformer, rectifier, or power transistors, can cause excessive current flow, blowing the fuse.
2. Overloaded Circuit – If the amplifier is connected to a speaker with an impedance lower than the recommended value, it may draw more current than designed, causing the fuse to blow.
3. Faulty Power Supply Components – Defective rectifier diodes, voltage regulators, or capacitors in the power supply section can lead to excessive current draw.
4. Internal Component Failure – Burnt or damaged transistors, ICs, or other electronic components may cause high current consumption.
5. Wiring Issues – Loose, frayed, or shorted wires inside the unit or in external connections can create a fault condition.
6. Incorrect Fuse Rating – Using a fuse with the wrong specifications (too low in amperage) will result in frequent blowing.
### Troubleshooting Steps: - Visually inspect for burnt components or damaged wiring. - Check the speaker impedance and ensure it matches the amplifier’s specifications. - Test power transistors, rectifiers, and capacitors for shorts using a multimeter. - Replace the fuse with the correct rating and monitor for repeated failures. - Disconnect external connections to see if the issue is internal or external.
If the fuse continues to blow, professional servicing may be required.
