I have not turned mine over to see how warm it is with the front panel power
switch off.  Remember, it is normally left in the position of having the rear
switch turned on.  There is a power supply that may be heating your bottom hot
spot, but I'll let the official word come from Wayne or someone else on that.  I
can't turn mine over to see, since it is hooked up to many cables.

On the other hand, I've checked mine many times on the sides, front, and top to
see if there are any warm spots.  I use an IR thermometer, so it is extremely
easy and fast.  Mine is always room temp unless I'm "heating it up".  I also
have a thermometer in the exhaust fan "cage" to keep an eye on that temperature,
and I monitor temp on the amp's digital readout at all times I'm using it.

If there is any condition or location (other than the bottom) that I can measure
for you, spell out the conditions and I'll do it.  I use it daily.
