I have two things to run by all:
Since I "mount" my 756 into a cabinet I was concerned about cooling. 
I read the great article/web page with the temperatures on and about 
the set,,, since my cabinet is going to almost enclose the entire top 
and sides I wanted to protect the investment.  So i mounted a small 
3" fan behind the left rear vents. I used some r value to slow the 
fan to where it is not audible. The idea was to gently remove some of 
the ambient heat generated from the display & guts. It seemed that 
even out in the open the display & other front components were very warm.
With the little fan, which draws less than 200ma including the "r" is 
powered from the 12 vdc line on the aux jacks(pin7). I fused it 
also.   the front is never more than slightly warm to the 
touch,,,,   a cool fix for 3 $...
