There are 3/4" tall feet and the bottom plate is well ventilated. Cabinet is not enclosed, there is plenty of air coming in from behind as well. The top aluminum plate where the tube sockets are placed gets very hot. I am going to try a variety of tubes to see if that makes a difference. I had been using some Sylvania 6sn7 WGTA, brown base, chrome domes, these seemed to create more heat than the JAN-CHS Sylvanias.
