Thanks to all for your thoughts. I definitely worry that a 30-foot image will be too dim, but I feel that if you're going to do something silly like this, it should be as outrageous as possible. I'm going to do some tests. I'm planning on a home-theatre-geek-approved low-tech front surface screen made of formica, plywood or foam-core sheets painted with HTG-approved screen paint. I didn't mention that I have *several* of these beasts, all with really good tubes, so in theory I could stack them for a 2 or 3 projector blast, like we used to do with the old GE oil-film Talaria projectors. I used to use these CRT projectors professionally and know how that setup is difficult, but hey, so is restoring old TVs. With apologies to JFK, "We do this not because it is easy, but because it is a hoot!"
