First of all the AC line interference filter cap is a almost totally useless part...You can literally clip one out of nearly any working set (or other devices power supply) that uses one and the set will keep working without it with NO noticeable difference in performance...It may as well be called an appendix capacitor.
Capacitor tester depends on your needs. For solid stat gear I reccommend one of these ...
https://www.ebay.com/itm/All-in-1-LC...RSbR68buZCZFOw There are hundreds of them on ebay under a search for "ESR tester" pick your price point, vendor, and their home country (unless you live in china or hong kong buying one from a seller there is going to increase your wait).
If you need to test lytics to working voltages of 50V or higher get a Heathkit C3 (like mine) or some other eye tube based tester.
If you replace a line rated cap size don't matter much as long as the leads reach, BUT on top of the capacitance and voltage you need an X or Y rated line cap to go across the powerline otherwise the AC may ruin your replacement.
