As a vintage computers collector, I have loads of CRT monitors and TV sets. They are already showing their ages, but compared to my flat screen, they can be perceived as much more robust. Hands down.
Now, consumer products from the 1980s may also be rubbish compared to the 1970s. I have taken apart tape decks, receivers, amplifiers from the 1980s that needed important components to be replaced while the 1970s counterparts needed a bit of TLC and nothing else.
Plus, I have this 1973 Phillips mono radio recorder that sounds warm, lovely, beautiful. I decided to leave its innards untouched as they are, because I could even spoil its magic. Its mechanical parts need all sort of fixes but it still works. Meanwhile, I have two high-end Technics decks from 1986 that don't even work anymore.
Your mileage may vary, it all depends on the devices in question, models and manufacturers, but from where I stand even cookers and fridges these days are rubbish compared to what we had way back when. My own cooker weighs as much as the cardboard in which it was shipped!
