I have 2 Braille Lite 40s, one of which I use in the shack for notetaking. I also use these for notes when I speak or preach. They're both in great shape except that they need new batteries. I suspect that they are old enough to have the packs soldered in. Do you know of anyone who does work on such things and can replace these batteries? If possible, I'd like to avoid going through FS but there may be no alternative. Thanks and 73. Lou WA3MIX
