Perhaps they just changed the type of power supply installed.

Hello,

I bought an R8B a couple of days ago. It had been powered up since then. It
is running very very cool. The Aluminium front panel is cool & above the
transformer the top cover is only warm.

If my memory serves me .....the other 2 R8B's I have owned ran much warmer
than this? Seems like I remember the front panel getting warm & the top
cover over the transformer getting warm enough to almost make the textured
paint soft.

I wonder if Drake has made any changes? The Serial # of this one is
3A12940004. I am running it off of the internal power supply.
