yhep. just looking for a origional tg-16 RF adaptor that came with the US system.
Here's a brand new one. (http://cgi.ebay.com/Turbo-Grafx-System-RF-SWITCH-Antenna-Box-NEW_W0QQitemZ330219560017QQihZ014QQcategoryZ49230QQssPageNameZWDVWQQrdZ1QQcmdZViewItem) It's not a horrible price, considering it's new, though a universal adapter would be cheaper if you're not set on having an original. Be forewarned: some people here have had trouble with redfrog, yet some people (myself included) have dealt with them without incident.
thanks for the link.
yhea has to be the offical one. its for a collection. have a complete in the box tg-16 only missing the origional rf box
