Most efficient vacuum tube

vacuum tubes use 3 systems coating to ensure the most effective heat absorption. This included a AL-N/AI layer but also a separate aluminum and copper layer.  The added layer conduct heat better and also stabilize the coating allowing for a much longer lifespan of 20 year or greater.
