All carbon comp resistors are replaced with high-stability carbon film (for noise reduction) but critically, the "Set.33" retains one specific carbon comp resistor in the phase inverter to keep the "bloom" and sag that tube rectifier lovers crave. The coupling capacitors are upgraded to SoZo Mustard caps, which smooth out the harshness of the vintage distortion.
