As Dug says, FET's are voltage rather than current driven. At DC they draw no steady state gate current. You could feed them via 10 or 100Meg, but that would be no good for audio...
At AC you have to supply (or have available) enough current to charge and discharge the gate capacitance. Not enough and the output stage will suffer slew rate limiting and restricted HF response.

for a supply of +/-30V at the output how much will be the drain current from each output mosfet? since the bias is 2.6 amps so do we need to divide it by 5? so 2.6/5 = 500ma? for one mosfet?
so can I use 2sc5171 as driver for the 5 pairs at the output stage ?
