I have 8 of these fine connectors for the DIY crowd. They are solid billet copper:HCOFC: High Conductivity Oxygen Free Copper 99.94% Pure Copper and then Silver Plated. Teflon is used to separate the positive and negative connections and center pins are attached to a teflon piece in the center. The pins look bent but it is the tipping of the center piece in entirety. All connections are set screw. No soldering or crimping required. These are used and I cleaned them with acetone. Some residual Walker silver treatment inside the bowels of the wire recesses I could not reach. Enough to make 2 sets of cables. List price is $128 each. I will sell 4 for $250 or 8 for $500.
