[Boatanchors] A "bit" off topic - Thin Audio Output in Vintage SS Rigs

Sorry if this is a bit off-topic. It pertains to Boatanchors, but of
the non-hollow-state variety.
In the ~ 40 year-old SS ham/consumer rigs I've seen, made with discrete
components, the audio typically seems very weak and 'thin'.
Is there a general rule-of-thumb why this happens? Is this primarily
because biasing resistors are aging "up"; coupling capacitors are drying
up and loosing value, there's conductivity across the PCB, etc.
In my limited experience, by contrast, the hollow-state BAs generally
retain plenty of audio output, even when not in alignment or having RF
