Emac 800mhz ATI

[macbaz]

I have been given a broken Emac 800mhz, white door... it is supposed to have a new ano board fitted but still can't start up, it is dead as a dodo.
I have checked plugs cables connectors and PRAM battery, i have found that the internal fuse has blown, so i put in another and it blew again as soon as i put the power plug in the wall.
I have checked the Fan assembly with a ohmmeter and it reads ok with zero's.
Advice please what should i be looking at next, what would blow the fuse ? its out of warrenty , so i need to do it myself?
Also where can i get parts for Emacs?
Thank you

If the fuse is blown every time you plug it in, my best guess is the powersupply.

Thanks for your reply, do you mean the "Down Converter board" ?

is it a starndard fuse? if so someone may have replaced it with an incorrect one if someone with the same emac could post the spec on his fuse you could check before shelling out for a new power supply

Another thought, and maybe a silly one: Is the voltage switch in the right mode? Don't know if there still is one, on the newest Macs it automatically switches to the correct mode.

I have checked and i think the voltage is set ok, but i can't find any where to find the spec on the Emac 800 ATI internal fuse.
The fuse at the moment is a small ceramic 6.3v!
