For completeness, I measured the ESR of my new capacitors, from the extras in my batch, with my Cap 1B ESR meter and this is what I got:

Through-Holes:

~ 1.5 Ohms ESR:
Rubycon 100UF 16V https://www.digikey.com/en/products/...FC5X11/3134106

~ .2 Ohms ESR:
Rubycon 47UF 50V https://www.digikey.com/en/products/...6-3X11/3563118

~ 1.9 Ohms ESR:
Rubycon 22UF 50V https://www.digikey.com/en/products/...15X11/11312828

~ 1.9 Ohms ESR:
Rubycon 10UF 50V https://www.digikey.com/en/products/...R5X11/11312740

~ 2.9 Ohms ESR:
Rubycon 3.3UF 50V https://www.digikey.com/en/products/...R5X11/21738993


SMDs:

~ 7 Ohms ESR:
Nichicon 47UF 6.3V https://www.digikey.com/en/products/...MCL1GB/2551077

~ 4.5 Ohms ESR:
Nichicon 22UF 16V https://www.digikey.com/en/products/...MCL1GB/9452736

~ 20 Ohms ESR:
Nichicon 10UF 16V https://www.digikey.com/en/products/...MCL1GB/1963909

~ 8.5 Ohms ESR:
Nichicon 4.7 UF 35V https://www.digikey.com/en/products/...MCL1GS/2549603

~ 6 Ohms ESR:
Panasonic 1UF 50V https://www.digikey.com/en/products/...1H1R0R/1985150

I'm comfortable leaving my PCB populated with these, but it was a good thing to document this before I attempt testing them on the Y/C PCB again, if it is ever failing in the future. All except one are higher ESR than my meter's manual suggests a working capacitor in this capacitance range should be. These are obviously new and working, though.
