I have worked on quite a few CL-30 and CL-60. Yes the transformer does get quite warm. I also remember the power transformer being close to the output tubes. They are designed to run at that temperature and if there was an issue with too much current being drawn through the transformer your line fuse would fail provided the fuse is the proper current rating. You might want to consider replacing your filter caps at some point. I've had to replace those too.

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.
