Features

CUSTOM TOROIDAL POWER TRANSFORMER

All PrimaLuna products use massive, potted toroidal transformers in a metal housing with non-microphonic resin in order to further reduce noise and to protect the windings from moisture and deterioration forever.

BAD TUBE INDICATOR

If a tube fails, the PrimaLuna Adaptive AutoBias will instantly put the amplifier into protection mode so no parts can get damaged. A red LED will light up in front of the tube that needs replacing. Simply plug in another tube, and listen. Absolutely no guesswork.

CUSTOM SUPER-WIDE-BANDWIDTH OUTPUT TRANSFORMERS

Output transformers are the most important part of any tube amp.  It is there to extend tube life and with bandwidth to bring slam to your system.

AC OFFSET KILLER – A PRIMALUNA EXCLUSIVE

PrimaLuna custom-winds our own massive toroidal power transformers that are low in hum and EMI. The AC Offset Killer lowers transformer noise resulting in a sense of space and texture. The resonance of an acoustic guitar or violin string seems to trail on forever. The AC Offset Killer will bring you goosebumps.
