As the title indicates, I'm a newbie with the A7. I have really enjoyed it on my REO grand. Until now, that is. I have a Phoenix, and am somewhat familiar with changing the coil on those. That said, I thought the posts on the A7 were connected to the body, and that you unscrewed the screws to slide the old coil off and the new coil on. When I went to do this on my A7, the entire post unscrewed, leaving me no way to attach a new coil. Is this normal, and if so what gives?
