The output section uses (6L6GC or EL34, switchable via a bias voltage adjust).

The is a hybrid document – part classic tube amp topology, part modern microcontroller-driven bias management. Understanding it requires familiarity with both vintage Marshall power amps and digital control loops. For modders, the Infinium section can be bypassed (convert to fixed bias), but the stock design offers reliable, maintenance-free tube life if all low-voltage supplies remain stable.

: An onboard Atmel microcontroller and voltage regulator that continuously monitors tube health, negating the need for matched power tube sets and automatically adjusting bias. Input Configuration & Signal Path The output section uses (6L6GC or EL34, switchable
