I am selling the estate of a doctor who left a treasure trove of home theater equipment. His son left it unopened since 1995. In some cases, I cut the seal before I realized I should not. I feel for the man who retired but never got to use his great stuff. These things need a good home. The list is amazing, but for this forum I mention an eleven foot box with Electriscreen on it. See the picture. I also have a silver Novabeam, which is 80 inches diagonally. See the second picture here. I don't know how properly to take this one down to ship it. Could you tell me? And thanks for looking. Please comment here on these for me. I need information what they are for. And if at all inclined, please make an offer.
