Here is another one. This amp is based on the JEL Simple 45 circuit, relatively simple to build. Now, I have built more complicated JEL circuits, and I have to say this one is a real gem. Just pure joy to listen to. The 45 coupled to James 6113HS OPTs seemed to have done the trick. I don't know, it just sounds really good! It takes a lot for me to say this. I gotta look into the 45 more. Here are some pictures:
