Very clean and fully tested Stereo Preamplifier.  This has audio input stereo pairs for Tuner, Phono (Magnetic Cartridge Low Level), Aux 1, Aux 2 and Tape Deck.  Has variable out to amplifier and a fixed out for tape recorder.  Everything works and it looks fully original. I deoxidized the controls and tested everything - static free, hum free, hiss free!
