Denny,
I took your advice and moved the AC-4 to a floor location outside the
MS-4 and let it run all day. It is pretty warm but not too hot to
touch as it was before. No fan needed now. Thanks for the reply.

Considering that there is no direct intake, I would blow air onto the
supply. I personally have never felt that much heat coming from the
supply. I do not have either of my AC4's mounted in the MS4 housings.
Maybe that is why I don't have the problem. I do not use fans either.

Subject: [DrakeRadio] AC4 heat
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?
