Fuse blown in KEF PSW 3000? Pls Help! (1 Viewer)

[Raakky]

Hi.
I have just received my new PSW3000 sub today, and when i was installing it I somehow managed to switch the fusebutton from 230V to 115V. Im currently in the UK, and it should be 230V. Now the subwoofer is dead, and I am hoping it is "just" the fuse that has been blown. I do not know how to change this fuse as it is not reachable on the back.
I would hope, and beg somebody here can help me, eventually have some experience with the same thing!
My worst case scenario is that the whole mainboard is gone, but then again why have we fuses for.
Regards
Morten

Did you buy that new? Over here on our side of the pond...it shows circa 2002-2005...

No not new, but bought in Ebay, was in an ok condition. You dont by chance know if the fuse is sitting right behind (inside) of the fusemarker on the backside?

I managed to chance the fuse today after an operation inside there.
BUT, now the sub cuts out at higher volumes. It works perfect at very low sound. Any ideas people? IS there something unfixable that is wrong?
I hear a click inside the speaker, then before it comes back i hear a click in the main board. Sounds like something is shorting, but i have checked almost all the wires in the mainboard/amp board. Cant see any burned things, loose wires or anything broken.
What can it be?
hoping you can help me

The only way to "check" the driver itself is to connect another amp to it after you bypass the internal amp. Then if the "problem" goes away...the plate amp is definitely fried.
