Audio Research VS110 Middle transformer gets very hot the 2 sides not so is this normal


After about 1 hour of play the middle transformers gets very hot  you can touch it but bearley 
the 2 side transformers nearly warm .
my question are 
is this normal or an issue in the making?
Is it safe to keep it on for 4 hours or not ?

Thanks for your advice

the right speaker is louder than the left ( not by a crazy amount) but currently there nevertheless
would this be an amp issue - prep amp issue  or speaker issue
I will switch the right & left speakers to see if it a speaker issue
but how would you distinguish between the amp & pre amp
You can use the same technique. Take the preamp outputs and reverse the left and right into the amplifier inputs. If the right speaker remains louder than the left, you'll know the problem isn't with the preamplifier.
