hello thomas,
i had a problem with one of my 143-2's that was sold
very easily.
just check this:
unmount the module from the rack and insert a minijack
cable into one of the adsr outputs. then obnserve the
module from behind the face plate. maybe the tip of
the patchcord's minijack is touching the led's pins
that are running very closely behind the minijack
socket
regards,
Bakis.
