Hi, can anyone tell me how the electronic astig (maybe on an XG) works?

I am interested in the pure technical thing, like what is really corrected electronically (2 pole or 4 pole or both), how the magnetics are constructed (wound), how it is realized to do the complicated rotation of the magnetic field done by turning the manual astig knobs and rotating them arount the neck to be electronically adjusted...

Best Regards

Roland

First I thought about the GP-3000...

Just have to measure the diameter of the 5000s neck, but I think it is too big for a PG+ focus coil.


Yesterday I got a set of SD-116 and wonder what? They seem to have electronic Astig rings.

But only 2-pole, so it is still more intersting if the hicher end 8"ers like the XGs and G70 and the later M8xxx or the PG+/x have 2-pole dynamic or 4 pole or both...
