fisherprice turntable

Does anyone know how to build in a headphone amp in this fisherprice portable turntable?

I read dj Format has had it done where the DC-input is located.

i 'd say splice into the speaker with a headphone plug.

it has a speaker out put right ? then just tap into that source and modify the hole for the plug thru the plastic casing some how.

It looks like it has speaker..So couldn't you just run a headphone jack off of the where the speaker is?..They sell all that stuff @ Radio shack for cheap..Just a suggestion could look into I guess..Let us know what happens..
