Default Bad chip resistors?

That said, mostly I find such faults confined to cracked carbon resistors.



** Small carbon film resistors regularly fail (open) due to high voltage "tracking" between turns on the spiral cut. Plate resistors in triode stages for one.

IME - metal film and cermet types ( ie chip resistors) are less prone to do the same.
