Here's a question for the Kustom Amp experts: I have a 1969 Kustom 200A Guitar Amp with 15 " Jensens. I realized recently that one of the 15 inch speakers was not functioning. When I opened up the amp, I found that mice had gotten into the amplifier during the ownership of the previous owner and chewed through two of the wires going to the coil of one of the speakers. So I had the wires re-soldered at a speaker shop. Can anyone tell me what the capacitor that is attached to the cabinet was used for and whether it's necessary to be hooked up? It was not hooked up when I opened the cabinet, but I figure there's a purpose for it. It appears to be original to the cabinet.
