PrimaLuna

PrimaLuna was founded on the idea of eliminating tube maintenance. They do this by using a sophisticated Adaptive AutoBias system while running tubes at minimum power, while giving more slam and bandwidth through superior output transformer design.
PrimaLuna employs Point to Point Wiring on all products. The entire signal path, including resistors and capacitors, is painstakingly hand wired with heavy-gauge cable by craftsman.
