Description
You are bidding on a pair of Sylvania type 932 radio/audio tubes. I had not encountered these before, but data shows they are electrometer tetrodes aged for grid stability. They are 4-pin tubes with a top cap. I do not have the settings to test them, but they do show good filament continuity. The previous owner has written "Great" with a 1995 date on the sides. One was found in a smashed box, and the other with scratches in the black exterior coating was loose. They are not identical, as one has an extra support at the top. They are interesting tubes for your collection, or for use. Shipping weight is 8 ounces. Please see my other listings for more radio and audio items, and tubes.
