Biggest engineering mistakes in audiophile gear

Hello,
I have been in Africa and Asia for long holidays ( 10 weeks) many times . It is not only the number of kids being born that is a problem but also the lack of skills, space and means to properly raise them. If you go to a big city like Ho Chi Minh . Compare how it was 20 years ago ( few cars just (motor)bikes and now still a LOT of motorbikes but every year more cars. Most parents supply their kids with phones at a very early age. When parents visit a restaurant with kids( usually they do because they cant afford a nanny) whenever the kids get noisy they are silenced with a phone.
China one child policy was not good at all but two kids should be stimulated.
Just like with Brexit we need a few years to make a decent evaluation.

Going back to the origins of this thread, I recently acquired a Music Fidelity Electra E10 ( a work college was going to bin it because of a buzz on one channel ), my intention was to replace the power caps, and if this didn't work just use the casework, switches etc with a cheap class d board. So I replaced the two 10,000 uf 35v caps with multiple smaller 35V caps. When this was done I decided to check the voltage - 40 volt. So I replaced all the replacement caps. At least it now works ok, but WHY did Music Fidelity use 35v caps? It's a wonder they lasted as long.

I’ve seen many cases of caps being under voltage. In really old equipment it’s often because the line voltage *was* lower back then. Even then there wouldn’t be much headroom. Probably cause older caps would really take more than rated voltage - even for 2000+ hours. They were physically bigger for a given rating back then, as you have seen. I don’t think I’d push my luck with modern caps.
 
Hello,
When i was a kid when visiting my grandparents they had a big hard cover, nicely illustrated Alice in wonderland. A series of glossy like big picture books each of them showing paintings from the painters young age until passing away.
They also had big collection of complete weekly magazines to show me how life was when they were young.
My grandfather told me about double clutch gearboxes.

Hello,
One of my English teachers who really admired Bertrand Russell ( indeed an Englishman) must have influenced me to much in the eighties.
But know we dont need someone like him to see that reducing the world population would give us more time to find the shortage of food and resources taking us down.
We could start by eating less livestock.

As Eduard implied, one child hasn’t worked out well for China. Sure, easy to yell “reduce the population” but like almost everything, the consequences of radical change are hard to predict. Now the Chinese government, and the single kids can’t afford to support all the aging people that dutifully (or else!) had only one child.

So quick change isn’t tenable and slow change might not happen fast enough...
I guess this should be in the “biggest social engineering mistakes” thread!

I had a single child and it wasn’t a “cold, feel lonely” experience for him or us. In fact he says he liked our full attention, and my wife and I have always been very close to him, even now that he”s over 30 and live far away!

I think kids should be simulated, that would solve a lot of problems.

You know what? I read this previously as "stimulated" 🙂 Thinking stimulated to learn, study etc. so very positive. I only now read it again to read "simulated" 😉

It is sad to see those wanting children not being able to have them and some that are able neglecting theirs. There was a documentary here about 2 disabled parents with addiction habits and very low intelligence that kept on making babies and every single child was taken away as they did not know how to handle a baby. The father was interviewed and he said:"we will go on till we are allowed to keep one". AFAIK only one of the daughters was "normal' now even taking care of her own mother that only likes to use social media and smoke. It really made one think that it would sometimes not be a bad idea to test people if they are up for the task.... Others even wanted forced birth control which is quite drastic.

That is a sad girl a little too obsessed for that age IMO. Today I learned of this (in Dutch but I hope that will be forgiven):

Warning, long read. It seems the solar fields that literally pop up everywhere are also just a business model absorbing tax money and revenue going to investment companies. Somewhat on topic as the situation is worrisome technically as energy is generated at around the time that there is least demand causing severe instability issues in the grid 🙂

BTW I was in wind energy a while (technically) and I can not see the positive effects in the long term. 3 blades of each 15000 kg epoxy and glass discarded after maximum 10 years to be either buried or worse, burned (far away but the air does not stay there). Production is not safe health wise either. When we think the cycle starts when they arrive in a harbor shiny new then we simply think wrong.
Totally understand your point. Issue is, you will not be able to convince 99% of people out there to switch to a zero-consumption (or zero-lifecycle-footprint) lifestyle. Wind turbines probably won't be part of the final solution but the overall carbon impact is IMO worth it. Besides, wind and solar (with the current energy paradigm) are pretty much the cheapest ways to install new power now.

I can't read Dutch and am too lazy to run the page through Translate, but there are lots of places in the world where power needs are not saturated with solar. Even then, investing in energy infrastructure to share power and stabilize grids is almost certainly going to pay dividends...

I can better live with plastic garbage in landfill than I can dwindling insect populations, higher risk of pandemics, eco-political instability (don't even want to get into that), etc.

You forget the N-word! Nuclear.....

I agree with or understand your opinions. There is much to be said/decided and much more to be done.

(Psst, another cause of dwindling insect populations is the wind turbines...)
