O Gauge members thanks again. I immediately ordered the Lionel 8v Adapter.
The DC adapter with the Legacy Base & Remote as a set. I will be looking to find out why it was sold as a used Set.
My Legacy Base & Remote is correct and my Adapter is the 630-7156-010 9v AC. Also sold as a used set. So I'am ok.
Amazon is selling the 12v adapter as a replacement for the Lionel adapter. All kinds titled as replacements for Lionel adapters.
