Totally forgot that all the gain from the Aegis is from 6SL7 input tube. Yep, rolling tubes on this won't change the max SPL that this amp will do, but will impart the tube characteristic of the output tube. Currently rolling a KT66, just the sexiest tube on the tetrode family IMHO. The blue hue looks so cool as well!
