Can you tell how long original Sugano cartridge suspension would last? I have an eye on original Black MkII and Onyx. They were not played for several years (5-10) and stylus looks very good under microscope .

I might be wrong, but basically the suspension in the Sugano (long) Koetsus tend to go wrong after around 10 years. I've seen one in which the suspension rubber became like a jelly after 5 years.
The long Koetsus are rather old, so my guess would be that the suspension needs to be reaplced and if you are unlucky, then the coil will also have to be recoiled as it would be not possible to change the suspension without harming the coil.

How are the coils connected..?? I suspect the two coils with the same orientation are in series..
The brick is in soft iron, for best performance i guess silicon-strip-steet (transformer-core iron) or maybe Permadur would be the best choice. The iron core gives the B-field direction and higher Flux.
