Hi,

Well Venkat thanks for recommending my name !

Now tell me what kinda Amp you want build ? offcourse 100W is the very basic detail that you have already mentioned ! I mean is it for a pure two channel Audio or is it for Sub or whats the purpose ?? reason is for each application there are different topology to be used !

Please do let Us know for Us to comment on the Amp !! Also please mention your skills at the soldering front and basic electronics ! Please don't mistake me for asking,its just that I don't want to suggest something complicated to you thats all !!

Regards.

Um here are the details... I'm going to use it with the computer ... it has got a sb live card with 24/96 output..it should feed two speakers and a sub maybe...no I don't need a sub... an eng graduate i know all the basics ....

Hi,

Ok but one small confusion !

it should feed two speakers and a sub maybe...no I don't need a sub...

What you mean is it should give line out ??

Anyway the Amps which will give 100W are plenty, as already suggested by other member in your other thread there are IC based and discrete devices based !

The IC based are LM3886 or the TDA 7294 Dmos chip based Amp ! both are fairly simple to build and have been raved for their quality sound !

The Discrete route is bit tough ! but if you are upto it then you can try variety of designs in that ! though the preferred type is Class AB for in general ! so anything in that design will do ! for the components and other kits your preferred destination is Ritchie Street Mount Road or Radio market in the area ! go to a shop called elektor kits ! its in the first floor ! they have some solid Amp kits ! all of them are from elektor UK so The original UK design and sound !! or else go to the keen kits opposite Torvin office in seliyamma koil street of the Radio market ! its a sister concern of Torvin and they have all the assembled Amp Boards,so you have to do the rest !

Let Us know any more info is required !!

Regards.
