heres a monkey wrench...
if the faceplate is actually higher than the top panel of the enclosure then would not the height of the rubber feet of the preamp on top be "absorbed" as part of the measurement? Probably not too clear on my part but the picture of the combo looks like the top plate sits a little lower than its faceplate does and therefore if its true than the estimated total height of both units together is:
fullsize power supply = 2.75"
preamp less the height of the feet, say only 2.5"
for a total of 5.25"
Guess I don't have enough work to do if I'm contemplating this
