I became used to favour power amp saturation over pre amp distortion... Power amp saturation is where the best tone is. This amp had a drive pot that was giving too much pre amp drive, and by the time the power tube overdrive started, there was way too much pre amp distortion over it. Maybe suited for some styles... but not for me...
I decided to improve the tone a bit, so the amp had more power amp saturation and less pre-amp distortion.
Removed the drive pot altogether and replaced it for a fixed filter that did not overload the second stage too much, keeping it clean and punchy. Also changed the resistance from the second stage to the phase inverter, alowing 3 switchable positions(including stock value), allowing me to drive the phase inverter harder, and pushing the power tubes into sweet organic and punchy tone... Great blues tone!
Also upgraded the ceramic tone caps with silver mica, for sweeter highs.
Another easy to do improovement was to use NOS pre and power tubes... its really a big change in tone... I am more and more convinced that new production tubes, even JJ's (wich are the best tone IMO), cannot get  close to any NOS tube... I mean those things where meant to be reliable, and new production tubes lack both in the durability, strenght, and tone department... The amp became alive afther I swapped the power tubes from JJ to german made NOS... Great tone with an alnico speaker or greenbacks.
