                                                    Russian Military Selenium Rectifier                                        Brand new. OLD STOCK NEVER BEEN USED. Selenium rectifiers are made from stacks of square, or round, aluminum plated.  Each plate is able to withstand about 20 volts  in the reverse direction. The metal squares, or disks, also serve as heat sinks in addition to providing a mounting place for  the selenium disks. Plates can be stacked indefinitely to withstand higher voltages. Stacks of thousands of miniature selenium  disks have been used as high voltage rectifiers in television sets and photocopy machines.      Radio and television receivers used them from about 1947 to 1975 to provide up to a few hundred volts of plate voltage. Vacuum tube rectifiers  had  efficiencies of only 60% compared to the 85% of selenium rectifiers. They are ready to operate instantly, unlike vacuum tubes, which require  20 seconds to warm up.
