Carl--  
It does get softer when it's warm, and when pinched between stuff (as it would be if run under the board) it can cause shorts. I have actually tried to run the plastic-insulated wire under the board with this result. Cloth-insulated wire does not have this problem, and can even stand the temperature of a soldering iron on a nearby connection for short periods without causing a short. The plastic-insulated wire also doesn't stay where you put it, thanks to the stranded wire inside, unlike the cloth-insulated, solid-core wire.... I would guess that the plastic-insulated wire is also le$$ co$tly, a feature that always gives the bean-counters lumber.... :D

I'd venture a guess that the cloth wire started costing more and it was a $$ driven choice.

Bruce--  
I preceded the whole thing with "IMO", which means that I'm putting forth a possibility that I consider to have at least some merit and that some seem to have overlooked.  
 
I don't remember where I heard that bit about the UL condemnation of cloth-insulated wiring, but the fact remains that the circuits wired with it didn't need parasitic oscillation caps, while the amps using plastic-insulated wire (and the change in lead dress that accompanied it) did need them. I suppose I could have mentioned that the UL bit was something I'd heard but couldn't back up, though.... Judging from what else I've read and heard about the CBS management of Fender, the co$t difference reasoning wouldn't surprise me either. :D Either way, CBS screwed the pooch on that one. :(  
 
 
 
BTW, Anyone out there know where to look for info in the mid-1968 era of UL history to check the story out? I, for one, would like to know for sure one way or the other.... Does UL have a web site?  
 
This leaves one unavoidable fact--the new layout, regardless of who is responsible for it or why is was changed, rearranged the capacitances between elements of the circuit all over the amp badly enough to cause oscillations, so to think that it might have also changed the tone is a fairly small and easy leap.... Remember, everything's capacitively coupled to everything else--it's just a matter of degrees! So, have fun with the concept that you are capacitively coupled to Claudia Schiffer (I am he as you are he as you are me and we are all together--who'da thunk it that physics would prove Lennon right?). Oh, and try not to retch over also being capacitively coupled to Bill Clinton's "intern test probe".... :D
