"i m using a 30-0-30, 8 amp transformer "

With two pair of outputs that might get you as much as 120W/4Ω and power a second channel too.

You might get as much as 200W/2Ω; but that would need very good heatsinking, high-performance insulators, and you might consider a third pair of outputs.

I would use the TIPs rather than the BDs, and use 10Ω in their emitters rather than 100Ω.

Adjust the bias until you have 0.34V across the base of the outputs (the 10Ω resistors).

hi sakis,
its not a DNA issue..big amplifiers are too esxpensive: true...but not a local problem..simply, we are new in this world and in starting everything is crude,big,blunt and powerful .Later it will be sophisticated,delicate,accurate and so called audiophile.Believe me when you are listening a 2000 watt rms audio system you are more inclined to feel thump than detecting it class ie.A,AB or B.At least my ears can not differentiate between classes of amp on higher volumes.
thanks

thanks formula 22,

you made my amplifier even better, i would do the changes and mention the results later.
Earlier in the original circuit i set the bias to 25mA, output shows only 1mV, amplifier is dead quiet, no hum, no hiss.

what could be the ideal bias setting as you have included a trimpot in the schematic you updated.

Regards,
Aniket
