• Notes
• The 4000 Autocorrelation Preamplifier was a collaboration design by Bob Carver and Bill Skinner.
  It was designed to expand or uncompress the sonics of recorded material. In audio parlance, it is called dynamic headroom. In the midst of all the knobs and toggles was the four channel balance joystick.
  The 4000 had the capability of controlling up to six components: a tuner, two tape decks, two turntables and an auxilliary.
  It had three switched and three unswitched AC plugs.
