I see your point and agree Techknight. But I remember an espionage case from the 1990s which affects computers today. This case involves capacitors, where a mole in a USA Electronics  firm stole the designs for a more efficient cap and sold it to the Chinese where they started to flow the market with these caps. Problem is, the mole only got 1/2 the design and the Chinese caps would leak within months of use. Years later the same thing happen to a Japanese Electronics Firm where another cap design was stolen and sold to the Chinese where they flooded the PC Manufacturers with these caps with more disastrous results - blow up on the motherboards after 6 months or so of use. Once again, it was only a partial design plan that was stolen.

The market is still flooded with these bad caps, and people like Uniserver managed to get a name for one of them, ENLA as used by Apple and other PC manufacturers. I'm sure that the Audio market has these bad caps too. But there are many good caps out there, lasting 20+ years. My Sansui Amp is from the 1970s and its still going strong with no issues with its caps, though I did had to replace a couple of final transistors in the past. My Blaupunk Car stereo which I had with my first car in 1981, has went from car to car to car is still going strong. As is my Cobra 148 CB Radio, with so many mods on it I can not post them but it is modded to push out 12 watts instead of 5, has not shown any problems with caps and I had it since 1986. As far as my ancient computers are concerned, my Commodore Vic20 and C64 are going strong as is my Apple II/IICs and Laser 128.

I want to see what Uniserver has to say on these repaired power supplies and how long they lasted with just a few caps replaced.
