A lot of factors come into play. quality of the original tube, filament voltage, plate screen voltages, power cycles, even heat (ventilation). while tube have a finite lifespan. under proper conditions , they're pretty robust. output tubes in power amps live a tougher life!.

Preamp tubes are easily identified, in most cases, as the smaller bottles in your amp, and are usually positioned to correspond to your amp's inputs and early gain and tone stages. sometimes they are covered with metal shields, which are easily removed. since the mid fifites, preamp tubes have mostly been of the smaller ninepin variety. The 5751 is a great sounding plug and play replacement for a 12ax7. the ecc81 12at7 has a gain factor of about 60, but it can sound a bit bland and more often shows up in phase inverter or reverb driver applications. the ecc82 12au7 has a gain factor of just 20, so it’s unsuitable for guitar preamp duties.
