Take the plug out of the back of the case. Immediately above the 
where the plug fits is where the fuse is, you'll need to lever it out 
with a screwdriver or the like, from underneath. The fuses are not 
ordinary 13-amp plug types, but special 'time-lag' ones. (It would be 
as well to check the one in the plug too, to see which has blown.) 
Maplin sell the time-lag ones, so I'm sorry to say you will probably 
not get it going again straight away - use the time to try and 
establish what happened(!). If it's not an obvious wayward piece of 
metal shorting something across one of the boards, then it's hard to 
suggest what it might be - generally all modules have short circuit 
protection built in, because the very act of inserting patch leads 
tends to short things momentarily to ground, so it's unlikely to be a 
loose or dangling lead. You could try taking your current patch apart 
lead-by-lead to see if you might have wired up something in a non-
nice way (though again this Doepfer stuff seems pretty unburstable 
from that point of view, so I think this is very unlikely). The only 
time it happened to me is when I was using it power something on a 
breadboard - I connected an op amp the wrong way - and it blew the 
fuse in short order (chip still seemed to work though!).
