I tend to adjust my methodology according to whether I think the part in question will
lead to catastrophic failure or not, e.g. power supply caps, high voltage decoupling caps
where a cap short to ground will take out an inductor that I cant easily replace.
Then there are those parts that you know that if you place them, you will have endless grief,
like in VFOs/PTO's, temp compensating etc.
