Soviet tech had to be built for serviceability - people couldn't often afford new things and even if they had the money, there was no guarantee it was even available. And many things just broke down constantly. It even went so far that "a set of golden hands," meaning one could fix a lot of stuff was a valued characteristic in males, and women sometimes may have overlooked other personality flaws in a relationship because of it, like drinking.
My grandma had a Soviet TV well into the 90s and even early 2000s, maybe out of sentimental attachment more than anything else. The thing broke down constantly, every 3-4 months at least, and she'd always call a repairman. In the end I think more money was sunk into it than a brand new 4K TV would cost now. It was finally laid to rest when her usual TV repairman died, and the new one found it increasingly difficult to find replacement parts, and finally gave up, and we could at last get her a new TV.
also there were significant sharing of tech between military industry and consumer (one can say that in many areas the consumer one was just a minor branch off the main military industry, kind of a USSR version of COTS). TVs and control boards of cruise missiles used the same electronic parts and were built using the same skills/processes - the consumer parts (like transistors, etc) were just the ones that didn't make the higher quality military bin (the military binned parts were marked "VPK" - "Voennaya Priemnaya Komissiya"/"military quality check", and these ones you'd prefer to use in your own electronic projects when/if you could get them).
I bought a Miele washing machine in 1996, and it's still being used today. It was about twice the price of machines that I'd had to before that never seemed to last more than a few years.
I'd also like to see a good data set of real prices of appliances over time.
Edit: Here's some examples of 1950s appliances: http://www.thepeoplehistory.com/50selectrical.html
Washer + Dryer in 1953: $494.90
Average monthly wage in 1953: $ 3,139.44 [0]
Average monthly wage in 2013: $44,888.16
So a 1953 washer+dryer cost the same amount of labor as a $7076 washer+dryer today.
