The fact that both channels exhibit the same symptom, at least that is what I understand from your message, points to a power supply issue. It may not be so serious as it seems. I would suggest looking for an experienced servicer in driving distance if at all possible.
And no question, Audio Research has produced some of the most significant benchmarks in tube amplifiers for more than 40 years. I have owned and worked on more than a few, and they definitely among my favorites.
