a few years ago i bought a bluestar platinum range. that's probably the closest you're going to get these days. it's all gas + mechanical, all stainless and iron, works during a power outage, etc. i looked around and didn't see any PCB's, just wiring for the lights, igniters, and convection fans. the broiler is a gas salamander style top grill.
... it was $6000 for a 30" range but it's more powerful than anything other than commercial gear. you really do have to pay up for simplicity. iirc it was more expensive than the equivalent wolf, viking, etc. and weird european brands like la cornue don't make 30".
most people say they're willing to pay more for this kind of thing, but very, very few people actually do. it's also made in the US, another thing people claim they will pay for, but usually don't.
