Hi All, a long time lurker, first time poster here!
I have recently finished my Mame cabinet project and as I got so much info here I would try and give a little back.
My cab took a little over 3 years and still isn't really finished. Not because it is complex in any way, its just, well you know how these projects get forgotten about. I am happy how it has turned out and love owning a cab. It is great to get you hands on the proper controls! Its not a beautiful cab by far but it is very close to the design I had stuck in my head. I used Google Sketchup to design it.
Anyways, please have a look! I have created a website full of info, files etc here.
http://megamame.creativemule.co.ukI will probably lurk about for a couple of weeks if anyone has any questions. Once again many thanks to anyone that contributes on these boards, I don't think it would have ever got built if it wasn't for the tips and inspiration.
