All,

Has anyone experimented with using bleeder resistors on their power
supply to bleed both the + and - rails after turn-off?  A discharge time
of around 1 minute should be fine, but I'm sure >2W resistors will be
needed.  I've read that using bleeders helps extend the life of the capacitors by fully discarging them before they are charged back up.  I do not know if this claim is true.

Do bleeders on the power supply alter the sound in anyway  

Thanks for all your feedback,

Vinnie

I would have thought the PS caps would discharge anyway, when you turn the power off, because the + and - rails are connected to the amp PCBs?

On my system, anyway, I used LEDs on the front panel to show me that each rail had a charge and these LEDs slowly dim when I switch off the power.

Andy, I also use and LED for each power supply, but I have them hooked up to each -36V rail.  Does this mean that the +36V rail caps are discharging slower than the -36V caps?

One side seems to discharge slower than the other ... but it might not be anything wrong with the caps.  From memory (I'm not at home right now) I think the + rail LED takes much longer to dim ... but this could be because its LED's electrical properties are different to the - LED and so I should have used a different resistor.  Or, it could be the AKSA circuit is not "symmetrical" and there are more parts which use electricity on the -ve rail, so the voltage drops quicker?
