Hi.
What did we do for many years without an ESR meter? We used the scope to look at the ripple and then decided to replace the capacitor, visual is useful too and feel, a cap that is getting warm could be failing and due for replacement, Bulging and leaky caps its obvious they are shot. Good ESR meters were expensive many years ago and the penny pinching accountants would often block requests for new test equipment.
