I have to share this story. Someone at work had a grandfather (MIT) who worked on the original Trans-Atlantic cable. Anyway in the 30's he built a system (mono) of cascaded push-pull 45's with interstage transformers ending in a speaker mounted in a closet door as a baffle. He tested his oil bath capacitors by charging them up and shorting them with a screwdriver. He claimed the ones with the loudest spark sounded the best. I guess he was measuring the ESR in an indirect manner.
