ESR is still relevant for the smoothing caps and output valve cathode decoupling caps, though.
I'm not sure on the precise relationship, I was told a few years back some high capacitance readings I got were the result of high ESR. I don't know that for a fact. I tested a few waxies recently that were showing double their capacitance on the multimeter, yet next to no leakage even at 350v DC though, which was surprising.
