At one time Doug was offering a new Super Elto coil.
I don't know if that is still the case.
I've never had one of the RBM coils out but it looks
like the primary and the secondary are wound on
separate laments between the shoe's. I wouldn't
think it would be difficult to rewind them for
someone that has the equipment to do that but
there is often a big difference between thinking
and knowing. Epically in my case.
I have one rewind, just for my self
I know a guy in the Netherlands who has the skills to do this work
normally, it is always one coil but in this case, two coils in a
120 degree ( ? ) angle and connected with each other !!!..........
he took it as a challenge
first , you have to make a tool, to fit it properly into your machine
second , you have to deal with the unbalance when it turns around
and yes , it was a bit expensive
( what the heck )
