Yes, of course.
As soon as I will know a lot more about my problem, I will post. But for the moment, my friend ( the specialist in magnet ) is in Switzerland for about 2 monthes .
As my problem will not be solved before several monthes , I think that I will order a new 275ND immediatly . Where can I find one at a good price ?:
And if my deffective one can be repared, I will keep it for spare.
Thank you for your help.
