Hi Riccardo!
I was just in Italy last week—what an amazing country you have 
!
Fryette does work with reputable local repair shops. We have a repair technician in Germany; would that be an option? But if you have found a local shop, please follow these instructions and ask them to do the same. Can I get my Fryette product repaired at a local repair shop?
Moreover, we can provide technical support directly to your technician if he joins the forum or contacts us directly.
Regards,
