Perhaps I'm just a wuzzie, but does anyone know a good reason why the MX-20 Adapter, such as this one, http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=585&item=6517670432&rd=1&ssPageName=WDVW has exposed B+ pins? Were there never any reversed sex ARC connectors made? I've never seen one, AFAIK. -John
