tweaking a class AB amp - Click HERE for Original Thread

Hi all.

I am new to this forum so bare with me. i am kind of a noob when it comes to audio but i have build a class AB amp based on BD 139/140 transistors.

it amplifies arround 60 watt and plays very good. But i talked with my teacher and he said that it could play even better if i had better effects transistors but i dont know how to see if a transistor is better for the purpose(this is problerly still because i am a noob) so i was hoping that someone could reccomend me some. prefereable would be arround 100-150 watt output per channel.

if you need schematics or any other information about the amplifier please say so. I hope this can be a good start for me making alot of DIY audio projects so it would be nice if my first amp would perform good.

BTW i am building a pre-amp for it atm based on the tda2415A if that can help.

Cheers

I suggest you post this request on the Solid State forum,
where more people are familiar with the BD139/140

:cool:
