I was in the Air Force for 20 years and lived most everywhere. I found that Europe had pretty reliable voltage, but I would recommend that you have some protection. You have a large investment and they like us have issues at times.
I had a multi-system TV and VCR then, and since I traveled so much I always made sure that most equipment was 110/220. I found most electronics still worked, (Using a transformer) but the clocks were always slow, if they were not rated for 50Hz.
