First of all, I feel really dumb. I recently upgraded from combo setup to pre/power/cab setup. As part of this, I've been trying out a bunch of preamps to find the one that best suits my needs. Good news: I managed to get a used Warwick Quadruplet at a good price. Bad news: Due to a chronic piece of transatlantic French / English misunderstanding, it needs 230V. I did ask about this before the purchase, and thought it was a dual voltage version but it seems like we got our wires crossed. I've emailed Dana B Goods here to see if it's possible for them to convert it. Should this not be possible, I'm guessing I'm going to need a step up transformer to run it. Anyone have any recommendations?
