I want to replace all the electrolytic capacitors before I prod anything else. It's working this well on mostly original lytics? New ones could make all the difference in the world.

That depends.... I have a Heathkit C3 cap tester that can test for leakage at up to 450V and capacitance from the pF range up to 2000uF, and have tested many caps with it in many sets. Pre-1960 stuff has a ~90% failure rate, but post 1960 stuff often has less than a 10% failure rate on lytics. It is not uncommon to find period lytics and many of the tubuars in a set like that still testing and working like a new cap...When they test good I leave them.
That set I don't think I tested anything but the PS doubler lytics and some tubulars since it did not act like it had bad PS caps.
