Hi guys,

I pulled the jamma board of of my project pictured below:



I love the way that this project came out, but there are a couple of upgrades I want to perform on it (make it smaller, and remove the 12v dependency).

Can you tell me on the board pictured below, where is the audio amp?



Is it in the below region?



Would this work similar to a mv1-c where you need to remove the audio amp & then cut the lines on the back? If so where on the back would I find the lines I need to cut?







Also provided I can find the right lines to cut, where on the parts side would I be able to pick up the left/right audio lines?

I'm asking for generic & specific help on this, because I want to perform this mod on this board and also on a upcoming mv1-b project that I'm working on. Any help will be greatlly appreciated.

I definitely don't claim to know alot of stuff, but I can do some stuff, so please be patient and understanding with me. Thanks so much.

Jeff

That is definatly the audio amp chip. Here is a link to the data sheet it gives sample circuits and should be close to what they have done on that board (if not exact). You should be able to figure it out from there.

Pas,

Thanks for adding to this post. That PDF definitely looks like it has vital information in it. From my 1st pass it looks like figure 16 might have the information I'm looking for.

Unfortunately, this information seems to be a bit over my head, thanks for giving me the benefit of the doubt that I should be able to figure it out, but I think you're giving me a little too much credit.

I really hate to beg, but can anyone assist me with this project a little more in depth? Thanks
