Ok, how do I calculate how much resistance I need? And is there an optimal position for it?

why?

the F5 is a ClassA amplifier and it draws continuous current even after the power has been switched off.

Have you measured how long the caps remain fully charged?

No, not yet, I'm in the process of designing one. So, you think I don't need it?
Wouldn't it help with speaker protection when turning off?

Is there a problem sir?

My guess was that if on turn off the resistor drains the caps then no power left in the rails.

I asked twice for an explanation, now if you don't want to reply, it's your ***** problem,
but if you do then keep your tone done. You don't know me, as I don't know you.

You imply that I said something REALLY stupid, and this is your brilliant answer that outsmarted me?! Right!


Some time ago I read something that Wavebourn wrote (if I'm not mistaken). He said the "wiser" give their knowledge with open hands to new comers, and then not treated accordingly. That they get a lot of bad reactions. Well this is not what I've seen here, and it happened to me a few times and also read same reactions in past conversations between others.
