    Edirol FA-101 blown Elna capacitor

    The Edirol FA-101 is a multi-channel firewire audio interface. It features 2 microphone inputs, 8 balanced inputs and outputs, optical digital input and output and MIDI among other things.

    It had a blown Elna 10V 1000uF RJF series cap in the power supply sections. See attached picture.

    The capacitor was causing awful squeel sounds in audio streams along with repetitive clicks. To be fair, this unit has been powered almost continuously for the past 3 years and has never given any other issues. Replacing the cap with a 16V 1000uF Samxon capacitor fixed the problem.

    What series was the Samxon replacement capacitor? Hopefully not a GF series, which is unreliable.
    My first choice in quality Japanese electrolytics is Nippon Chemi-Con, which has been in business since 1931... the quality of electronics is dependent on the quality of the electrolytics.

      I actually replaced it with a KM series (which is general purpose - not low ESR) just to make sure there was nothing else stuffed in the unit. I have some 1000uF 16V Rubycon MCZ caps on order now to replace the Samxon.

      Thanks for alerting me to the GF series though, I was unaware it was bad.

      Cheers!
