OK, I just rebuilt 2 Avanti Sigma 5/8 and found out that what Sacramento Sonny had said about "Some do, and some do not have coils" was correct.

I wonder if it was the earlier or the later production which had no internal coil? Did they get smarter or cheaper in their design & production?

Supposedly the version with the coil was quieter due to passing static to ground better as it had a DC path to ground through the coil.

Anyone know the real story here?
