Subject: Way OT: grounding MOTM w/ step-down TF

From: Aaron Day <aaron@...>
Date: 2003-01-30

Greetings-

I'd like to connect my MOTM to my old Macintosh power amp but am concerned
about the grounding.

The amp is a 110v unit w/ a 2 prong power cord that is being powered by a
step-down transformer (I'm in Germany everything is 230v) and I'm concerned
with my health....

As it stands I have a small mixer (connected to a 230v outlet feeding its DC
transformer) on the input and would like to attach the MOTM to this.

At the risk of sounding a bit slow, would a star-ground (from how I
understand it) keep me in the safe zone? I was planning on running a ground
wire from each device and clamping it to the buildings old central heating.

Perhaps this is overkill? However I've been juiced here a couple times and
one of the shocks knocked me to the ground--thus my angst.

I know we've been through different scenarios before but I haven't seen one
that covers this issue. Any links or suggestions appreciated.
