Never has so much concern been given over one solitary capacitor, just
replace it and be done with the discussion. If the same amount of attention
went in to the thousand or so other components on the radio then this forum
will go on for the next 500 years.

There are components that are much more problematic, yet we do not even
discuss them. With the abundance of crystals in the radio it is more
challenging to find a replacement in the same package size. Another
challenge is the debate over carbon comp, carbon film or metal film
resistors in the RF/IF chain and how self inductance changes a tuned
circuit.

If you lose a transformer then it is all-over, done-for; yet we do not
discuss how to protect a transformer from overcurrent (B+ fusing) or inrush
current limiting.
