Any thoughts on if a matching transformer should 'click' when the key is released... Obviously it is likely an inductive reaction to the rapid change in current supplied... When I connect the 48V supply to the system the finals don't last long... OK at 12 and 24V so I feel it is a inductive kickback that's blasting the 200V rated FETs...  The system works great into a 6 ohm load driver pushpull without the match xfmr...  It must be the inductive kickback...
Perhaps the inductance of the windings it too great?
Damn physics... To quote a power engineer friend of mine "it's a damn shame that FETs behave the way they do, otherwise they would be the perfect device..."
Class E time?
