[Drake] [Drakelist] AC4 heat

[James]

I hot glued two small 12vdc computer fans to the back of my AC4R which is in a MS-4. One pushs air, the other sucks air out. Results is a cold AC-4.

A while back I recall a discussion about the heat in the AC4/AC4R. Now 
that my rig is back in the shelf along with the PS in the MS-4, I 
notice that the back of the AC4R is too hot to touch for more than a 
couple seconds. I worry about cooking the xfmr too much.

I could put a fan on the rear apron, and if so, is there a preference 
on the location? Also, would it make any difference which direction 
the air flow goes?
