The other caps in the ampnot electrolyticsare for interstage coupling of the audio or tone circuits and should never pass dc. Taking my symptoms into account would it be advisable to replace the power amp chips as well. Blog Posts How To Tell If Your Tube Is Bad Thetubestore Blog How To Test A Pool Pump Capacitor Inyopools Com In aluminum capacitors this induces more leakage current due to the aluminum oxide layer slowly dissolving into the liquid electrolyte. Amplifier capacitor failure symptoms . Capacitor failure modes experience has shown that capacitor failures are second only to semiconductors and vacuum tubes in components prone to malfunction in electronic equipment. As this happens the leakage current of the capacitor can be high especially when it is first energized. Capacitors for ac applications range from high voltage oil filled devices such as ...
