now you have made me look very closely, and I'm wondering if it does actually have an adaptor that is somehow fused on. I had tried to unscrew it without luck, and then figured it was not an adaptor. I really don't know how to tell. I'm not sure how to attach images to the post--I haven't ever done that before. But I took a few with my iphone.
Also, it was a nightmare to log on--forum kept saying I didn't have valid credentials even though I reset my password.
