Hey Guys,
thanks for all the input. I really am glad that this didn't happen during the shoot.
I will be sending it in. Maybe I'll have Kortwich - I'm in Berlin - take a look first. If they can repair it, it would be less than half the price and way faster. Sound Devices had a store in Berlin, they closed it in the last months or so, so I would need to send it to UK. UK sends it to US - at least for the next two weeks -, they repair, send it back and I guess about a month later I'll have it back.
I'll report back, it might take a while...
