Ah, some additional info. I have used the older Eichmann plugs in the past. If the KLEI use the same plastic material, I would be careful when soldering on the ground/shield pin. The plastic material tend to melt easily and can skew the ground pin. I would attach this plug to an RCA input to act as a holder/heatshield while soldering. Also, sorry if I'm repeating info you already know, but when connecting/disconnecting this type of RCA plug, always push on / pull off directly. Never twist this plug when connecting or disconnecting from equipment as it can bend the single ground pin when you do this.
