Re: Are the Pearly Gates scatter wound?
The effect of scatterwinding, at least as I understand it (whether deliberate or accidental), is at least in part to reduce or otherwise alter the coil capacitance and thus sweeten the highs. (There may be other things that scattering does that I don't know about yet.) The layers of coil criss-cross each other kind of like a ball-of-yarn (as opposed to nice neat rows), so instead of one turn of wire feeding the next with its current leakage (capacitance), it may skip several turns and have spots on its length where it can't leak current into another layer at all or at least less than it otherwise would. At least that's my theory...
However, this does NOT mean, nor did I ever intend to imply, that a machine-wound/machine-guided wind can't sound good. You can create the same effect as the above with a very precise deliberate pattern, as long as it's not in perfect neat rows that allow the maximum leakage of current from one turn of wire into the next. For example, if you had a computerized winder, you could program its traverse speed and RPM's so you got a steep pitch (angle of wire to bobbin plane) that would create a very exact geometric pattern -- sort of like a lattice or trellis -- but which would create the same or similar layer-skipping/capacitance reducing effect as scatterwinding. But because the pattern would be very exact and anything but random, it would by definition NOT be scatterwound.
I don't know, nor do I claim to know, nor am I in any way implying that I know that Seymour or any other manufacturer does or doesn't do this. I can only say I suspect it might be something in their bag of tricks but again, but that is all.
