Leaky capacitors need replacement?

Thanks to everyone for their help, by the way.

Also, I need an axial version of that Nichicon and mouser has gone mental it seems.  I keep getting 403 errors.  Deny me will you...

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?

I keep getting 403 errors.

Try this it’s the 2nd one

It’s a Music Reference RM-10 and he should use the exact value for the replacement. I can't remember the brand that Roger used, we may still have some lying around, but the Nichicon’s pointed out by George are a good choice and should fit inside. They were one of Roger’s favorite capacitors. As for getting someone to put them in any competent local tech can do it.
