I have been a long time owner of an Audible Illusions 3
pre and never had the trouble you are describing. It seems that there is a problem with the circuitry, perhaps too much power is being funneled into the tubes when warming up occurs. The AI tubes are always on, a small bit of current is placed through the tubes to keep them warm. This actually extends tube life. I would call AI up, explain the problem & see if it could be fixed. The AI preamps are what gave the company the name, it shouldn't function as you described.
