I'm sure that's true. But there's a lot of expensive copper in those boat anchor 50/60Hz transformers. And thanks to dumping-level Chinese component prices, the electronic route is usually way cheaper. Parenthetically, paradoxically, and similarly: from what I've read, the digital electronic controls on the fancier household gadgets, such as microwave ovens and electric space heaters, are actually cheaper to manufacture than the less-featured old fashioned mechanical timers and thermostats. I suspect -- but don't know, not being an engineer -- that if they were designed more robustly and built with higher quality components, the reliability of the high-component-count solid state designs could be brought much closer to that of the boat anchor transformers. But then they'd probably cost as much or more. And maybe the constants in the equation will change when the upcoming US tarriffs on Chinese components and subassemblies (but apparently not on finished Chinese products, go figure!) kick in.
