The texture knob is to switch the amp between class A and A/B.. completely different from a power soak.
The texture knob alters the distortion and tone of the amp, and even though it will control the output of the amp to some extent, its not nearly as efficient as a power soak, where you can get your power amp tubes smoking at bedroom levels.

It's not a soak, it does pretty much what it says it does: changes the texture of the attack and sustain.
