Yes, I know Les Bosher in England. He seems to be a good eclair technician. I am not sure he has knowledge in Arri cameras, but I'll ask. I could send the camera to Germany, but their servicing would not cost less than 2500 euro on this camera. Les Bosher is a good idea. Thankyou.
PS- You can have a look at the SRII, if you wish: it is there: http://art-medias.com/PA.html
I am eventually selling it, if you know somebody who would be interested.
