Hi Guys
I seem to have caused some confusion, I've re-read my post and still not quite sure how. Whatever it is nothing was intended.
Yes of course i'll pay, can't imagine someone doing it for nothing.
Asking as im not an electrical enginner, i just fix computers for a living and this is a bit outside my knowledge.
I did have someone who was going to design the circuit and make it up on SMT but im afraid they have let me down.
I have today purchased a schmatic from information unlimited which seems to do the job. Not sure if i can post as they sell them though.
Will need a few mods as it does,nt have any way to adjust the volume.
