I have a question about the results from this program.
Using an ideal voltage-controlled switch in LTSpice, I simulated Bobby's example of a 75m KW http://classeradio.com/tools/nu2b/PushPull_KW.doc unit on the Design Tools page http://classeradio.com/tools/nu2b/nu2b_download.html of ClassERadio.com. Everything looks good, except that the full output power seems to be drawn twice - once from each DC supply - which cuts the efficiency roughly in half.
Am I looking at this the wrong way?
