Thanks. Yes, the connector (barrel) is breaking down, intermittent within the molded strain relief. I've cut strain reliefs open before and tried to solder the weaken strands of wire, but would just like to cut the old barrel plug off, and splice/solder and new one on. Then again, 9VAC PSU are plenty plentiful. Used to have a plethora of unused old cell phone adapters laying about, but alas, I must have dumped them in a spring cleaning.
