[QUOTE="CrunchBunch, post: 151096, member: 3591"] Interesting that the CLEAN module has 4.7k for the cathode resistor on V1A. What is the value of the anode resistor (should be R25)? A center biased arrangement for a 12ax7 is normally 100k for the anode resistor and around 1.5k for the cathode resistor which should you give you maximum clean headroom on that stage. However, increasing the ratio of anode to cathode resistor (by lowering the cathode resistor value from 4.7k to say 1.5k) will increase the stage gain and could result in more distortion at V2B.
