Well, given that the ventilation aperture in the sled and the vent holes in the empeg are on the top, don't you think it's a bit silly to obstruct the convection path out of the head unit by sticking the EQ unit above it? Blimey, no wonder it overheats !

Can't you put the EQ under the empeg instead?
