[Milsurplus] BC-342/BC-344 Question

[Joe Connor]

What's the current thinking on cap replacement in these receivers? I wouldn't trust the 75-year-old electrolytic caps in the power supply or the Micamolds located throughout the set, but what about the oil-filled bathtub caps? Do you replace them as a matter of routine, or do you wait until one of them acts up?
The triangular piece of metal attached to the Vernier knob has some rust. What do you folks use to clean and shine a piece like that?
As always, thanks for your guidance.
