Keith, some time ago I put some heat shrink tubing on the end of one of my IEC connectors. It worked pretty well. Heat shrink tubing comes in different thickness, you may have to experiment.
High quality "locking" IEC connectors?
Does anyone know of a high quality IEC connector (pure copper conductors w/plating) that actually locks into place? Something similar to the connection for a balanced interconnect? or maybe something like a twist lock connection? I'm sick of trying to prop up my power cords to ensure that they are connected securely. I've seen some lower quality connectors available but nothing with good quality copper conductors. This seems like such an obvious need in high end audio. Anybody have any ideas?
