Associated equiptment Sonic Frontiers 80, Proac Responce 2. Musical tastes,just about everything, Jazz, Blues, Classic Rock and of course Classical. Source components, Vinyl, 2 and 4 track open reel, and some digital. Gentlemen Start your engines, and again thanks for all the help.

You should talk to someone who knows, I am just passing along something I remember hearing, and that is that the Audible Illussions unit, through its design, stresses tubes much higher than almost all other designs and therefore severely limits your choices for replacements as many, many tubes will fail in this circuit in a matter of weeks.
Surfgod ... You may have had that experience with your AI with the factory tubes as they are selected to withstand the design - but choosing many of the standard NOS tubes that sound so good elsewhere may not be possible due to the "on the edge" design. Again, I am dealing from hear-say and someone else should elaborate on this point.
