Hi folks
Hoping someone may be able to point me in the right direction, I've got a basic knowledge of electronics but could do with some guidance...
I have a Mission E8AS1 Active subwooofer which is blowing the 1.6A fuse on the main input immediately on power on, even without an audio source or any volume.
If I disconnect the 2 boards downstream from the transformer, the fuse stays intact, but with the first board connected (crossover?) it blows. I identified two blown caps on this board, one of which was shorting (8uF 100V +-10%) which were hard to find, but have now been replaced (the two blue ones near the centre of the board are the replacements). However the board still blew the fuse even with the caps removed, and still with the new caps on.
All other components on the board looks fine to me, no obvious skid marks or bulges, the tracks are clean except for my novice soldering bodge where I replaced the capacitors. There was a bit of goop at the bottom of the blown caps which I have cleaned.
Can someone advise what I could test/ try next? I have a basic multimeter but nothing fancier.
Many thanks in advance for any advice, all gratefully received.
