Having followed suit, I was disappointed today to find a new/old-stock great fat 10,000 uF electrolytic giving an ESR reading of 0.8 ohm. Being, at least philosophically, Scottish, I thought I'd give reforming the dielectric a go. (My method is just to put the multimeter on ohms range, to apply a low voltage at low current. Mine emits + on the negative terminal in ohms mode, so reverse connection of the leads is needed.) When I came back later, the needle had crept up to full scale on ohms x 1, and after briefly shorting with a screwdriver, just in case, retesting gave an ESR of 0.03 ohms. I don't know how typical that improvement might be, but it does show that a capacitor oughtn't be ruled out at first glance.
