Hi folks- I have a Line Magnetic LM-211IA integrated tube amp that I am happy with. I am moving from US to New Zealand and am trying to find out what is needed to convert it from current 120V mains to 230V mains. I am guessing it may just be a jumper or re-wire of the power transformer, but I have not opened it up yet. The sticker on the back says "~115V 50/60Hz 230W". I have seen pics of EU units that say "230V 50/60Hz, 230W. Does anyone have any knowledge on this?

Thanks for any help!!!

A schematic for the 219iA shows a dual 115vac primary. Since these amps are marketed all over the world, it would be odd if they couldn't be rewired for 230VAC. Using two different power transformers wouldn't be cost effective. Have you emailed the manufacturer? Theoretically you could do it yourself, but you'd better get it right. ;-) If you don't hear from LIne Magnetic, you could take it to a professional. Might be worth it to be sure you don't damage it.

Thanks! Problem is I cannot seem to find any contact info for Line Magnetic. There is an EU distributor, but they don't seem to have contact info. I will seek some professional help! Any recommendations? I am in San Francisco. Also, if anyone has a schematic for the 211 that would be great!
