Well, I finally got around to completing the BLT - Balanced Line Tuner.  It’s not just a balanced line tuner though; it now will tune a coax-fed antenna, and a random-wire antenna, as well as a balanced-line antenna.  It was pretty simple to put together, although I had trouble a couple of times, caused by my shakiness.  Following are some photos of the building process.
