You need MIC preamp
http://www.diyaudio.com/forums/solid...q-preamps.html
or some mixer with MIC input.
With two pairs of 2N3773 you can get about 150W on 4R load +/-56V DC rail voltage.

u can use 2n3773 as o/p devices ,,,, and 2sa1943/2sc4793 as drivers ...... if that is nt available last option will be to use BD139/BD140 but supply voltage has to be restricted ....And as per I know o/p wattage will be higher than mosfet o/p stage... although increase in wattage is marginal
Shreya check ur Private message .............
