Hi, it could mean you need a real ESR meter after all. I brought mine only a few years ago and find it very useful, YMMV. Thought a capacitor meter would be good enough, should have brought 45 years ago !. My advice is purchase tools as you need them and will last a while, and stops you pursuring dead ends and reading theads about other so called ESR meters but not really performing any real test. Purchase and move on and enjoy your hobby.
