MICROPHONE AMPLIFIER

 This MICROPHONE AMPLIFIER is a "solid State" amplifier, out of the 1920s or 1930s. It has no tubes or semicoductors. This is a great "how dose it work" question for your engineering friends. When you order it send me an e-mail stating how you think it works. If correct I will send a new pair of needle nose piliers. It is in good shape, but shows a small chip at one corner. Made by S G Bown London. It is 6 1/2 inches wide, 3 3/4 inches deep, and about 5 inches high.
