scope waveforms?

Geez enzo, i heard ya the first time. LOL ! Seriously, thats what i saw at one point when i probed the speaker out and tried it with 470R at the PI cathode and then 2k. Look above....i mentioned "fuzzy lines" or something like that when telling chuck what i saw. I saw that when at 470R ! So thats gotta be why the change to 2k was such a improvement. The amp has a more musical sweeter tone and especially feel. With 470R it has what seemed like a bit more gain and a slightly dirty BAD distortion. It seems subtle at first but after you play the amp for a while you realize it's just feels so much better and sounds much more focused and sustainy. But why? Thats all stock marshall PI values except the filter cap. So why would a 2k cathode be so much better?
