200 W Power AMP

I made this power amp using 2SC 3280 power transistor. In this circuit get 200w out put using  50w * 4 = 200w  . when we consider above calculation each transistor can output 50w , 50w transistor multiply by  4 get 200 w output. actually  this circuit diagram can not get perfect 200w because i use  method to get more output using this circuit. It  is  call  as parallel join transistor , for transistor parallel by another four transistor . in this cause I m   satisfy about my experiment .

Because output gain is increase . I m  actually happy  about that. but the problem increase is much less than my dreams.I think  one transistor can 50w output  because i assume  eight transistor can nearly 300w output .but unfortunately it is not there.it can higher few watts. and gain is increase.because i can bet perfect Bass from using my transistor parallel system.

I am use 26v 0v 26v  (5 A ) full wave transformer as power supply ,3000uf 50v capacitor pair  and 3A Diodes to  get main power supply .


I m use four controller preamp for equalizer my preamp wave. controller include treble , bass, balance and master volume controller . preamp is allow this 12v power input. in this case i am using 7812 regulator to maintain my 12 voltage.

I am use 50w 12v halogen bulb for speaker protection.When high voltage come cross the wire , bulb begin to illuminate .

I am use 10 " as bass , 3.5 " as  mid range speaker, and 2" as tweeter in build  my speaker column.This columns have cross over  circuits. cross circuit  device is use to filter the sound by frequency .because speaker can provide awesome sound . I am happy  about my project Because i am satisfy about my creation .
