"Every vacuum tube amp in the world suffers from shifting DC operating points, and this unfortunately has remained a functional limitation and maddening sore point for amplifier designers ever since the very beginning of vacuum tubes. Consequently I had to invent a DC restorer circuit using a 6AL5 / 5726 tube; it eliminated every last vestige of DC shift, while simultaneously reducing distortion three-fold and vacuum tube idle power by the same amount. As Tim would say, "Nothing new under the sun", just the same, it's never been done before, and it works flawlessly.
My Audio Cyclopedia dated 1959 , on page 547, has shown that the Altec Lansing 436B compressor amplifier also used the same "a DC restorer" circuit that you have claimed invented, what a coincidence, used the same 6AL5 tube. Care to clear-out the smoke? Attached is the schematic.
From FrankieD's lips to your ears: Sunfire - a quiet box of endless power.
