OK, so when I was doing the chassis work over at a friend's house, we downloaded a few of Shannon's construction "thumbnail pics" onto his laptop in his kitchen, then took the laptop out the workshop. As we were doing our layouts, I noticed the extra pair of jacks on the back of Shannon's chassis and the extra toggle switch on the front. Hmmmm we said, wonder what that is for? After a long day of drawing and drilling, when I got home I checked out the site again, looking at the full suite of thumbnail pics and surmised that what Shannon had done was put in an extra set of switchable inputs... am I right? Has anyone else come up with interesting modifications?
