Believe it or not, I have problem finding a small 110V to 220V isolation transformer!!! No matter how I typed in the search, I get solid state converters. This is true on ebay and Amazon and Digikey!!! What happened? It used to be so common and cheap to buy a small isolation transformer, it's everywhere. Anyone has suggestion? I just want about 5 to 15VA ones, leaded. I could swear 20 years ago, you go to Tamura or EWC etc, you'll find them just like that!!!! To be specific, I mean real transformer with iron core and primary and secondary winding!!! I can't even take for granted here!!!
