Here is proof of why recapping is an excellent idea. The Grey capacitor below is well within tolerance with no ESR but is also a 50 years old Elna. Cut open to see the difference in a new cap. Compared it with a brand new Nichicon. The 50yr old cap was burned and way more dry on the inside. The Nichicon was heavily saturated with electrolytics. Some Techs will say its redundant or overkill to replace them all but I highly disagree. Lots of times they are also leaking on the underside where its not visible until removed. Fun little project. Keep your equipment safe and change the filters! STAY TUNED!
