B is smoother...rounder sounding.
this is a hard one...both are to die for.....
Lets see...a hard choice. One could argue the second is the real 67 because the smoothness could be a result of the well broken in caps. .......
But then again the first could be the real Plexi because of the sheer in your face power.......like Ed's amp.
I'd have to say....the real 67 is the first one only because of that...Those tranny's just had something...an extra push for lack of better description.
But I am the only one voting this way here...LOL...so I am probably out in left field. You guys are so much better then I at circuits. But I have to trust my own ears/logic here as off as they may be.
