Amp PSUs - Joule per Watt?
Posted: Mon Jan 01, 2018 3:53 pm
The Russian guy that once sold me the Russian monoblocks talked about a "recommended" ratio regarding the energy that the PSU (caps) could store versus the wattage of the amp.
Have anyone heard about such figures?
There's a controversy in our sector, where people claim the more - the better, whilst other argue that extra Farads do no good or even can make things worse.
I have a faint memory, but I have to consult that booklets that came with my amps to be sure, that our Russian friend talked about a 1 Joule per Watt. This could also propably be some sort of lower limit, but I am a bit lost.
PS. The reason I ask is that I recieve mails from a guy who know nothing about electronics and happily hooks up his high-Z headphones to his tubeamps low-Z speaker connectors and no says it will be too expensive to replace the faulty 10000uF cap in some amp (he gives them strange names, like Angle for Musical Angel) so he will use a 470uF ...
Besides, it could be helpful when designing PSUs if there are some kind of rules of thumb. (There's the PSU Designer, but ...)
