bg and suggestions of leaving the amp on

jarthel · 28th June 2007, 03:08 PM

this has been said countless times.

I am just wondering if the the statement is true for any use of a BG whether it's a decoupling cap or power supply cap and other applications that uses elcaps.

Thank you.

Well.... "wet" caps has a limited life time determend by age, Working Voltage and "On hours", so for that part you should turn your amp off......

However the Inrush current on the caps (when discharged) when turning your amp on again also "eat" some of the life time...

So the answer is

I believe people's reason for leaving the amp on is that BG loses their "break-in" if the amp is turned-off and needs to be broken-in again.

not sure if this is true hence the reason for this thread

Well, I think you can expect limited life expectancy regardless - who knows, maybe 20 years? That's far enuff in the future where I personally don't worry about it.

I think Nelson's X amps go into standby where the caps and psu stay on - when you press the front panel switch. I think he's keeping the front end warm and is not too worried about the caps dying too early<I could be wrong bout this..
