When making regular interconnects with shielded cable, I normally solder the shield to the negative conductor and only on the source side of the cable. Do I do the same with phono cables?It isn't clear what you mean here. Typically, you'd connect the shield at the preamp end, and leave the other end - be it to a source or an amplifier - unconnected. That's all part of the "star ground" concept, and how cable manufacturers mark their shielded cables for directionality.
