Wow I would definitely by interested in building an amp too! I just browsed through a couple of youtube 'how to' videos and they fascinated me and I find myself gaining interest! I have a lot to learn though (that's part of the reason why I'm here). Seriously, some of the terms that are used here leaves me dumbfounded. Thank god for google I can immediately look the terms up.
I am gonna have to bookmark this section and thread as I am sure my husband would be happy to have new pals to build things with. Let me know if you get something going.
Sometimes the best way to build something, like an amp, is to tear apart another amp just like the one you want to build. Reverse engineering, I believe it's called.
