hi roel,
so,it seems that the problem is in the case's bus
board!as all the new modules have worked in your
other(older) doepfer case,they seem to be ok!
as far as i know from dieter,yes, a wrong connection
to the bus board can lead to a blown fuse!
but,also, check that your new "defective" doepfer case
is set for 230 volts(europe)operation and NOT for 115
volts!
bakis.
