Well, I'll have to do some listening to confirm this. It's certainly better than without the feedback connection (I think), and I'm not sure there's much difference between the cathode feedback and global feedback in terms of bass control. Notice that the output terminals are reversed in phase. If you connect them in phase the feedback is positive (at least this happened with my output transformers) and you get a slight increase in gain and the bass gets very loose and ill-defined. If you tried it without getting the phase right, then the sound would deteriorate, I think. If you did have the phase right and still found the bass less controlled, I'll certainly do more comparative listening to see if I can hear it.I may end up with a combination of cathode and global feedback, such as in the article above.
