Choose and replace the right tubes

The lifespan of a tube principally depends on 3 factors: how much it is used, its quality, and the hits it is given.

When you replace the tubes, especially the final tubes, they must be "coupled" and we can see why in a simple example: the final of a tube amp is like a scale that needs to even weights to work good. The "weight" in question is the capacity of amplification in every single tube, which can be completely different even in tubes of the same brand. This is why to get our scale to work well, the tubes need to be chosen among tens and tens and tested at the tensions they will need to sustain.

When you hear that your amp is "tired", with loosely basses and from the overdrive "easy" and squeaky, write me, I will tell you what to do.
