It would be convenient to just plug the rig into the wall, but how quiet are these older switching PS?  Also, does the heat they generate affect the reliability of the radios at all?

I have both a 740 and a 745, both with internal PS. So far as I can 
tell, the rigs have more birdies than any kind of hash from the PS. 
<smile> The 740 has a hotter receiver and the first of my pair. It's the 
one I use for CW contests, and hears great. YMMV.
