Why should change the electrolytic capacitors?

  • 1 - Electrolytic capacitors are among the most important in an audio equipment and replacing them with high-quality capacitors from the factory will improve the sound quality
    2 - Electrolytic capacitors have life of work 1000-2000h then begin to lose their qualities
    3 - The use of Audio-Grade Capacitor Nichicon / Elna which are made specifically for audio equipment from high-end will make your machine in good times higher

What is audio grade capacitor?

  • This is capacitors specifically for audio applications. These are designed to give premium sound quality when compared to general purpose capacitors.
    Nichicon's MUSE series and Elna SILMIC II, ideally suited for first class audio equipment where qualitative and quantitative characteristics are required.

What you should know when you make replacement

  • 1 Mark all cables when separate circuit boards to avoid confusion in the assembly
    2 All capacitors meet on parameters of old, replace them one by one so as not to get confused!
