Fuse keeps blowing

Vivek · 5th June 2003, 12:44 PM

Hi all,
I have one of those all-in-one systems (500 W PMPO). It is about seven years old. There is one 630mA fuse and there are two 2.5 A ones. The first one keeps blowing. I cannot even keep it on to check for voltages. I have changed the 630mA one five times hoping my luck will change. But it has not. Obviously there is something else wrong with the system. Where do I start looking?
Thanks for any help.
Cheers,
Vivek

where going to need the model number and the brand name. and does this fuze blow the minute you turn it on?

The system is from an old Indian company called Sonodyne. The model is Uranus FM2000.
Yes, the fuse blows the second I turn it on. I just hear the thump of the woofers and the fuse is out.

Tried a slow blow fuse?

It's okay now. The output transistors were blown. I have fixed it. Thanks for your suggestion.

Cheers,
Vivek
