I am building a Nixie clock that will be powered from 110V wall power. The design is based around having this 110Vac as the input voltage, but I wanted to put an isolation transformer inline for safety.
This thing will maybe go up to 10W, so I don't need a huge high power transformer. But I cannot find a 1:1 small transformer. Are these not a thing? Am I looking in the wrong place? Or do I need to redesign my circuit to use a different input voltage?
