Replacing the fuse to a different rating or type is very dangerous! The fuse is blowing because something has failed and is causing an overload. The fuse is there to protect and stop whatever is causing the problem from overheating the Amp and causing a fire.

Now to what might be causing it to blow. In most cases it's either something in the power supply for instance the transformer or any semi-conductor such as diodes, voltage regulator or what converts the supply from AC to DC.
The other area that will cause the fuse to blow is the main amp section, the transistors etc of which will be found on the heatsink.
If you have an Ohm Meter you can test transistors with it and diodes. In this case it will show up well, for when you put the test probes to the terminals it will be just like you have touched the probes together.

Fuse is blown in circit board


Did you have a power surge recently? That fuse can't blow itself. If a power surge got you then I would say to pull the board and put another fuse in. Of coarse unplug the refrigerator first. This may involve some soldering to remove the caps over the end of the fuse. If you did not experience a power surge then you should probably replace the board. If a component on the board has faulted, then replacing the fuse would be pointless. Because it would just blow it again. Hope this helps.

I have an alesis transactive mobile, which persistanly blows the 3.15a glass fuse. can anyone help........? Thanks Jamie


Generally a blown fuse is an indication that something is wrong and needs to be fixed.
If it is happening while the unit is in use, it may indicate power leakage to earth, which could be a safety hazard.
Or it could be drawing too much current because of a circuit fault.
If it happens when the unit is first switched on it could be be because of the initial power surge.

All three conditions could be contributing to some extent.

It should probably be checked out by an electronics technician.

If it only ever blows the fuse on switch on, fitting a slow blow fuse could keep it in service, and may appear to solve the problem, but i would still consider having it checked out and a component fitted to limit the initial current surge, as was fitted in most cathode ray tube computer monitors.

No Power on 32" Panasonic


A slow blow fuse is also known as an anti-surge fuse the idea being any sudden "spikes" in you mains electric when you switch on would blow a quick blow fuse. Anti surge fuses are designed to tolerate any sudden initial electric pulse.

Home Amp fuse keeps blowing


This usually happens when there is a problem with the main power supply and is relatively rare. If you can post the make and model, I can give you some things to check if you are somewhat familiar with electronics.
