Yeah, the transformer I use for my Japanese 100V amps is rated for 1800W and it powers my 300W speaker amps that are driving hard to drive Magnepans no problem. Certainly the same transformer but for 230V will handle the 30W AIC-10 just fine.I have a 230v and I’m in the US. I bought a step up Transformer, in fact Riviera advised I try it first rather than shipping back to Italy to change it. I bought a reputable brand made in the US, I have no hum, no issues, and is silent.
Here's the one I use, only $150 (the 500W model is even cheaper at $70)
