The TC4427 diver ic's have arrived. The same night I tried one out. It was a success. The efficiency of the amplifier increased dramatically. Now the dummyload gets warm instead of the FET's. It is hard estimate the efficiency as the output signal is not a sinus nor a block. It seems I can get 25 watt output while the FETS stay cool.
I am not out of the woods yet as the ringcores of the output transformers get hot. New bigger ones have been ordered. So I have to wait for them to arrive.
