Leaky capacitors need replacement?

Are you saying to replace the electrolytics with new electrolytics or use something else? These are right off the AC mains between the IEC plug and the rest of the amp.

These parts are being used in the DC Blocker inside the amp.

They should be replaced with the same value and voltage. @timlub has mentioned some nice quality parts to replace yours, which have a tendency to do this long before their time.

I am not sure what amp this is inside, but the ripple current rating seems a bit low for a power amplifier.


If this is a DC blocker, I question whether the lowest impedance capacitor is the best choice. That means more high frequency noise is passed through.  Thoughts?

If this is truly a DC blocking capacitor for a power amplifier, then those capacitors are grossly under-rated for ripple current. That would lead to premature failure.
