[Boatanchors] SP-600 3 Wire Power Connection

[Drew Papanek]

I've been pondering connection of a 3 wire grounded line cord to the SP-600 
while retaining the SP-600's original 2 pin chassis mounted AC power 
connector.

As far as I can see, there are very few options.

1. Run the green (ground) wire out through the back of the original plug's 
strain relief and connect to chassis.  Ugly.

2.  Connect green wire to original plug's metal shell using one of the 
screws holding the shell together.  Use  a short lead with lugs to jump the 
other shell screw to chassis. About as ugly as 1. above.

3.  Connect green wire to original plug's metal shell using one of the 
screws holding the shell together.  Metal ring on plug completes connection 
to chassis via threads on chassis mounted connector.  Not as ugly, but 
unacceptable because the ring was never intended to establish connection.

4. Modify original connectors by drilling and adding a third contact.  Too 
much work, partially defeats purpose of staying original with original 
connector.

Has anyone come up with a better idea to use the SP-600's original power 
connector with a 3 wire power cord?  (Or do I resign myself to removal of 
the connector and installation of something better?)
