Wow, MM, it is great to hear the iPad One's Spotify still worked as of a while ago! That's good info and augurs well for A3 usefulness for at least a few years. Our iPad 4 plays Deezer and a prior version of the B&O app, but it no longer plays YouTube, for example; this is why I opted to not purchase an iPad 3.
The Dremel project was a success! The B&O switch in the back is in the fully retracted position in the picture below, and the adapter is fully inserted, and the A3 is playing from an iPhone X —works with the iPad Air 2, also.
Following some eye-sight fitment calculations, I've ordered an Apple 30 pin to lightning adapter A1468, should arrive in a week. I expect this will work.
By the way, a final-generation iPod Classic (color screen) charges from the A3, but no sound comes out of it. No sound was expected; charging came as a surprise.
