I was basically working the same with just the final .02uf cap and the feedback loop, I definitely plan to increase the final .02uf cap to at least .22uf. I'll remove the .33uf that I added and test for DC at the outputs, if there is none or the same as now (0.4mv) I'll leave it out. The other circuit I tried was no feedback as well, and while all the detail and bass was there, I thought it just sounded a little flat and un-involving to me, the stock board is more fun to listen to. So maybe I just like the sound of negative feedback, crazy as it sounds. Before I put the stock board back in, I bought a Pas3 Aikido circuit kit from Tubes4hifi, which I will try before doing anything to expensive, its going to have to be pretty good to top the stock board.
