In some of the amplifiers i work with capacitors inside are 30 years old so i don't actually think that Nippon made tests ...for so long life .....
Don't worry sakis... We don't plan to keep our amplifier for more than 10 years
What does that have to do with anything?
Hehe good question... Looks like we have built more amplifiers and have seen more circuits (of varying topology)...
When we have seen enough, sometimes we don't need to think hard, or to understand the math....

that has to do that you cant have a decent class AB amplifier without enough capacitance behind it

Tell me more Mr.Science.
So just so I am clear, lot's of caps = good tunes?
OK, got it, who knew it was so simple.
I don't see really the point of an argument or a decent conversation when someone is twisting my sayings .
never said anything like that..... but yes many of us here think that there should be enough capacitance behind a decent class Ab amplifier ..Capacitance on its own though will play some role there is many other things also
now comments like that from a tube guy is hard for me to understand and also how a gainclone has more mustard than any discrete amplifier is hard for me to understand too....

Little caps = hollow and distorted basses...
Try amplifiying an electric bass with an amp that has
ridiculously low value caps , you ll get the point..
Please there is no science anywhere in this thread, just opinions.
You re not exposing your opinion but clearly denigrating
like in your response to Jay:
Tell me more Mr.Science.
read carefully and try to understand

then compare how similar other commercial audio amplifiers are made ( of similar range )
evaluate if things that the specific amplifiers offers are more innovative or concentrates more technologies than others
and tell us an opinion about the subject if you have one ....
( the all point is that the specific amplifier has implemented a number of things that you don't often see in commercial or diy amps and with a very high rank of concentration .Also it is important since many times we have been told about from the real gurus of the forum but seems that most of us and many commercial manufacturers failed to follow so many rules in one amplifier only ..... )

Someone tried to compare an amplifier with yours, you dismissed it because it has a fan on the power supply, that the owner states never runs in his application.
The fan is there for protection and care when being abused in a rack/ PA type environment, say outdoors on a hot day.
At those SPLs and distances the fan is inaudible.
Now I have not heard that particular Crown, but I have heard one of your amps that was kicking around the neighbourhood a few years back.
It's nothing impressive, it sounds like an average $80 bookshelf stereo. Any science you bring forth to this "proper" amplifier will be misleading at best.

you haven't got an idea of WTF you are talking about ..
The specific ventilator is called a transmotor and has on the same winding that is used for the ventilator , a secondary winding that provides 2*18 ac for the protection circuits to operate .
Point is very simple if the ventilator fails obviously the protection circuit will not have any power to operate so no click .
So the ventilator is not thermostatic and operates constantly ...
Point is that the ventilator stops from mechanical failure stops rotating while the coil remains operative and still producing voltage for the protection circuits and the amplifier actually boils till failure
Had to fix 6 times the same problem in 5 years ( for six different amps ) ...Have you ever repaired any of these amps ?
