I note most of LJM amp boards use the Polymer electrolytic capacitors for the Input capacitor? ( I am assuming the one I show is one?) The value seems to be 33uF, obviously not easily swapped for a film type due there very large size at this value. From what I have read they are considered be quite good sound quality-wise and superior to any Electrolytic types even Bi-Polar? QUESTION: How do I find out what actual type this is please?
