HI anatech,
OK, the temperature is the first enemy.
My audio equipments, and many other ones, offers best sounding after 24 hours of heating (48 hours is better). Difficult to switch ON one or two day before. Theses equipments are powered all the time.
I'd think what you see in the field are failed caps, otherwise, you wouldn't likely be seeing them in the field.
Their lifespan is calculable, if you abuse them, they may not even last as long as you guess, but then there is always infant mortality as well which can lead to erroneous premature conclusions served as facts.
If you can't trust your electronics
to run all the time without marked degredation, or having safety issues come into play, consider they should not be run at all.
The standards you mention are a matter of perspective, yours are not mine for example, and to tell people
they're overbuilt, perhaps as some standard that applies to anyone other than yourself, isn't so helpful to people.
New, and even used, electrolytic caps will reform in the first few seconds if they're healthy,
minutes at most. While it is an ever evolving process the worst is over very quickly. However, it is painfully audible, as are continued changes which can span minutes, to hours, to months, to perpetually shifting
like black gates, well beyond what forming alone can explain, save for perhaps the last example.
If you can't hear it, then you can't hear it, but it is not the absolute truth for everyone. Perhaps that is a harsh reality,
but otherwise it's too much like being a passenger along for the ride while the driver refuses his surroundings. I'd recommend you just stick with the panasonic FM as it will meet
your expectations.
You would think on a forum with so much traffic, there'd be more experts around to discuss such matters objectively and knowingly.
IMO that is an unecessary put-down. Besides which you are not looking for objective input but subjective impressions.
Quick question,
Sometimes is difficult to find the right voltage, I need 10uf 35v, is it ok to use 10uf 50v?
I agree. By study the parameter values in the datasheets regarded the ESR you will still note, that in most cases the lowest ESR value is by the voltage value either 63V or 100V. Both by lower voltage value and higher value the serial resistance rises up.
You will find even examples, that a device with 4700uF/100V has lower ESR (and better sound quality in a power amp voltage supply) than 10000uF/40V and approximately the same ESR than 10000uF/50V
What is the reason therefore in general?
My conclusion by electrolytic capacitor selecting for voltage supplies is now the lowest possible ESR instead the highest possible capacity value within a certainly size. So sometimes better to choose only half the capacity if there is critical space proportions.

Yes, always use caps with voltage higher 10% or more than the actual one.
The ESR parameter is important, but other important issue is the ripple current.
As said before if we need to replace some cap, will be better if space allows with more voltage (not necessary must be exactly +10%) the important thing is not change the capacitance value so you can replace with the maximum voltage value without any problem.
As general rule (speaking about good electrolytic caps) I disagree bypass them.

I suppose than higher voltage caps needs thicks anode & cathode so better current ripple & lower ESR.
i try it too
I try it too, just have it 4 of them
sound great, but didnt know wheres to buy them again

Devided Class
Maybe we must devided (Popular) electrolyt capacitor here into
Capacitor Signal
- Black Gate N
- Elna Silmic / II
- Nichicon KZ / FG
- Rubycon ZA / ZL
- Sanyo Oscon
Capacitor Supply
- Rifa PEH 169 / 200
- Siemens Sikorel
- Nichicon KG
- Elna for Audio
so we will hear another opinion from some member
my exp in electrolyt caps 100uf 50v bpa300 by alexw88,
BG N - looks natural
BG F - looks less energy
Silmic II - add a little bit bass
FG - you dont need subwoofer anymore
Panasonic - looks a little bit noisy
after all i fixed solder the FG caps there, just appetite
