I'm really waiting for the three horned models to come out On page 494, in the second edition of From Tinfoil To Stereo, is a picture of an ad for a monstrous device called, "The Multiplex Graphophone Grand," and its maker is said to be the Columbia Phonograph Company. This machine came with three 56-inch horns, and a special crane to support them, three reproducers, three recorders, 12 Multiplex Grand records, and 6 Multiplex Grand blanks. Obviously, the cylinders for this machine had three sets of grooves and it looks like they were 5-inches in diameter. The text says the machine was made in 1898, or 1899. This huge Columbia carried a list price of $1,000. Has anyone ever seen one of these three-channel behemoths? Have any survived? Were they ever really made? As a fan of modern audio, I found the use of the term "Multiplex" very interesting, because that is the term applied to FM stereo technology. (Early devices used to convert mono FM tuners to stereo were called "Multiplex" adapters.) Randy
