I'm relocating from the US to Thailand in a few months. All of my newer gear can handle any line power it would encounter around the world, but some of my older gear wants to see 110V @ 60Hz vs. the 220V @ 50Hz that Thailand uses. I have found some relatively cheap, yet robust voltage converters that will bring the 220V down to 110V, but units which also convert the 50Hz to 60Hz are very expensive. Now I'm wondering how big of an issue it would be to run my old synths on 110V at 50Hz. It *seems* to me that it would not be a big deal assuming that there is plenty of filtering in the power supply, but I would hate to make a wrong assumption and damage anything. If anyone has had experience with this, I would love to hear your thoughts / advice... Thanks!
