An item marked as Showroom Demo was used by AV Luxury Group for customers auditioning equipment in our retail store. We rarely sell our demo units unless the model or finish is no longer available. We go to great lengths to ensure our demo gear stays in mint condition. If anything isn't perfect, we make a note of that and post photos. Demo items carry a full manufacturer's warranty unless otherwise noted.
Bad Tube Indicator
PrimaLuna engineers wanted to make owning a tube amp so simple you would have no excuse not to have your tube dreams come true.
If a tube fails, 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. ( ProLogue Classic illuminates an LED on the front panel.) Simply plug in another tube, and listen. No guesswork. No smoking amp.
Reduces the available power of the amp and runs the tubes hard, meaning shorter tube life and failures via "shorts"
PrimaLuna's Adaptive AutoBias is a true, smart technology employing an array of sensors to monitor tubes and make adjustments seamlessly in real time. More important, it is the ONLY circuit of its kind that is truly "adaptive" by addressing "tube pinch off" at higher volumes, therefore reducing distortion by over 50% and greatly extending tube life. Adaptive AutoBias is completely passive and NOT in the signal path. The result is low to no maintenance, long tube life, and the lowest possible distortion for amazing sound.
Point to Point Wiring
You spend a lot of money on interconnects. So why have the signal go right from the RCA jacks or speaker terminals into circuit boards with copper traces so thin you can hardly see them? What’s high-end about that
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.
Ask any seasoned tube-head what the most musical output tube is and they will most certainly declare it the EL34. Other amp manufacturers would love to use it. Only PrimaLuna, through our proprietary output transformer designs, can give you EL34 midrange beauty with top-end air that goes on forever. And, bass extension with so much slam, our amps are used to power subwoofers.
