I'm not sure if this is the problem you are having, but some Doepfer
modules have PC boards *very* close to the edge of the module and it's
possible that the power traces are shorting out against your case.
This happened to me when I tried to install a certain Doepfer module
(either the Quad ADSR or Triple Bandpass, I can't remember which) in an
Asys RS15 euro-rack.... the traces on the lowest PC board touched
against the case and shorted out the whole system. The worst part is
that it fried 2 of my modules and I had to pay $180 to fix them.
Now I don't know if the Doepfer cases are the exact same dimensions as
the RS15, but you might want to check and see if any of your modules'
PC boards can touch the case under rigorous patching conditions.
Usually when a fuse keeps getting blown, there is an intermittent short
in the electrical system... or you are getting really bad power spikes
from your AC line. I assume you are using some sort of surge protector
