Lives for gear
 

Hi
Considering the internal complexity most 'op amps' since the '741' varieties are incredibly reliable as long as the power rail voltages are not exceeded and the circuit design does not deliberately 'stress' them.
Failures are far more likely to be elsewhere in terms of poor connections or 'short circuits' which may ultimately result in component failure.
Rather than becoming an 'expert' through watching a chip being changed on Youtube it would be better to learn some basic failure modes of various components, at which point you will discover than probably 70 percent of 'failures' will be mundane 'poor connection' related rather than anything 'esoteric'.
