[Elecraft] KPA1500 operating posture

I have to temporarily re-arrange my amp table to troubleshoot one of my two amps.  The only way to do it is to move the kpa1500to my main desk and place it on its left side with the rubber feet.  I know heat rises but once the fans come on it should direct the heatout of the normal top vents.
