spending a lot of time on 40 meter CW during the day. High school was
out for the summer and I was busy building electronic keyers and
learning to use them.
I've had excellent results with the Neutrik REAN NYS231 connector
family. I use the NYS231G for all my 3.5mm cables. These connectors are
available from Mouser under their part number 568-NYS231G.

Oh, yes! I used to have my PR6 installed directly to the rear panel with
the double male connectors. Since my station interconnect is pretty
complex and uses essentially every connector on the rear panel, every
time I needed to access something back there the preamp was extremely in
the way.
