An individual contacted me (because of my SB-104 web site) and needs the transformer on the DC-DC converter board. If you have one I'll put you in touch with him and you can work out a deal. If you have a whole unit junker I'd be interested because I don't have any junkers and I receive parts requests often. 73 Kees K5BCQ http://www.qsl.net/k5bcq/
