I might add, with regard to this comment that he or Chris will juke the mags, check the flux in the gap, and call before continuing. We're shooting for 11,000 but 10,400 to 10,600 is a frequently usable outcome.

Part of our discussion centered around Altec documentation. He mentioned one of the 515series that some of Altec's literature showed at somewhere far in excess of 15,000 Gauss. (I apologize, I don't recall the number) He's done exhaustive examination of the files that came with the equipment and found engineering memo's calling into question this and many other numbers. It seems perhaps, that marketing often made up their own numbers. My citation of my own post from 2003 gives salient testimony to his point. The literature often sucks.

He zapped an original set of 416B frames today and got them to just under 13,500.

Interesting point:
Altec didn't adjust the settings on the zapper for individual drivers. They built the fixture to do the ultimate zap regardless of what they put into it. They met the engineering goals by designing the magnet core to provide the proper field at full zap.
