You might want to look into an amp kit to get you started. I think there are several places you can get them from. The only one I know of for sure is www.tedweber.com

This is a project that I would like to do as well some day as well. I have a lot to learn about electronics before I take on that task though. I'd be very interested to see what you find out and decide on, so please let us know what you find.

BTW, how's the Stiletto treating you? I still haven't had a chance to play one yet, but I look forward to finding one after reading what you had to say about it.
