Don't think any of it is dual voltage, my manuals just state 110. Although the yamaha lists varions versions, the north american version only lists 110.

That leads me to another question...

If i bring over the tv, and get a transformer to get 110, will the 50 hz thrown a monkey wrench into things? The TV states 110/60hz. I think this affects crt's but im not sure about the DLP.

Thanks!
