Is that the fet input by Floyd WVL? Looks like it is. Curious why you went with this circuit.

Those little square things are capacitors to ground and the diodes provide a little bias so that less drive is required....
The FETs are IRF840
As is appox 12 Watts sinewave is required for 24 volts peak to peak..
The cores are only about 50 cents each too....
To be honest the cores aren't too critical for the input circuit....
