I have an ancient Eico bridge that can test caps at rated voltage. If I can't reform an electolytic in a couple of minutes, and have to repeat it the next day, it's toast. Wax caps, no, don't bother, replace them.
Modern digital meters that measure capacitance at a couple of volts are useless for this purpose. May indicate approximate range of nominal value if you are otherwise lost and don't have a schematic.
Pennies. Replace all the caps and old carbon resistors while you are at it. Makes a tremendous difference when you get the set together again.
