What is worse, is that old amps can have several separate and distinct faults (hum, noisey pots, valve blown) & the customer only notices Good point. My amp (hifi) is cutting out intemittently, and I couldn´t find it. Repairperson says there´s nothing wrong, because the amp worked just fine for hours in his shop. Two days later; boom, cut out again. Finally narrowed it down to a speaker-protection circuit with a mind of it´s own (Hey, I´m bored, let´s protect the speaker from absolutely nothing!)
