Audio Research Classic 60 & 120 owners


For those who own one of those, does the power transformer (left one on the 120 and the center one on the 60) get quite warm to the touch after a few hours of operation? Mine get very warm. So much so that i can hardly keep my hand on it for very long. The bias setting is dead on with SED 6550C. Mine were upgraded by GNSC back in 2004.

This is not a new phenomenon. They have been warm like this for as long as i can remember. I had meant to ask other owners but never got to it until today.
Any feedback much appreciated.

I currently own a pair of 120; just wonder if the fans have to be constantly on, ie. the cage have to be on; how can you access or adjust the bias port which is located inside the cage?
Yes, the fans must be on in order to properly cool the tubes and the surrounding components.
Hey Hifigeek1, thank you for your reply!
So from your experience, please advise how to adjust the bias port as it is located inside the cage!?
