Adaptaplug polarity
This is just an FYI in case anyone stumbles upon it. I had a hard time finding the information I was looking for online for Radio Shack's Adaptaplug size A. I needed to know which prong was positive and which was negative (which was the 'tip' and which was the 'sleeve'). As you can see in the picture, the left prong when the plug is pointing towards you (marked with black) goes to the sleeve (which is usually negative). The right prong goes to the tip. Hope this might help someone!
