Dave, your power output estimate may be a bit optimistic. Recall that the theoretical maximum plate efficiency of SE class A is 50%. Practically, it will be somewhat less. So, if you were going to run a KT88 with 40 Watts plate dissipation at idle, the max output (undistorted) would be 20 Watts. I'd say if he got 15 Watts he should be happy. If you square-wave it, the output will be a bit higher.  

Bruce Well, John beat me to that response... -- 10/14/1999 5:22 PM
