Quoted from metallik:Someone else already mentioned and I'll repeat: transforming AC voltages isn't the issue, it's all the linear DC power supplies converting that transformed AC that tend to fail. A switcher handles those beautifully by comparison. Show me any WPC driver board that has all original components... IF you find one it'll be in a NIB or never-played machine.
Fair enough, but those WPC games are all very old at this point. All the modern switching power supplies are going to have caps, many of them shitty ones and active components that going to fail and probably at the same or worse age-points as the linear stuff. I have receivers and amplifiers that are older than most of my WPC machines and the linear supplies in them have held up beautifully, they weren't on for 15+ hours a day for years and years like a routed pinball machine but in home use I'm not worried about it. However I've had to repair switching supplies in two appliances and three flat-panel TVs in my house in the last year and they are all 10 years old or less. The original point is probably not about actually replacing a transformer in an existing design as I interpreted it when I read the post I responded to though.
Now, back to the shitty warranty and not replacing things outside of it!
