PrimaLuna EVO 300 Tube Power Amplifier
The PrimaLuna EVO 300 Tube power amplifier with EL34 tubes can be switched from stereo to monoblock through flipping a switch. The benefit of monoblock operation is the amp now has dual output transformers for the best coupling with your speakers, and the addition of a 2-ohm speaker tap added to the 4 and 8-ohm taps. There is also a matching preamp with the EVO 300 series.
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. No guesswork.
CUSTOM TOROIDAL POWER TRANSFORMER
The toroids radiate about 1/10 the magnetic field that pollutes music and obscures detail. Additionally, the absence of an air gap typically means toroids have an 8:1 reduction of acoustic noise. As transformers are the most expensive components in any audio system this is significant.
All PrimaLuna products use massive, potted toroidal transformers. PrimaLuna transformers are enclosed in a metal housing and then potted in a non-microphonic resin to further reduce noise and to protect the windings from moisture and deterioration forever.
CUSTOM SUPER-WIDE-BANDWIDTH OUTPUT TRANSFORMERS
Output transformers are the most important part of any tube amp. We use lower power to extend tube life, and bandwidth to give you slam. PrimaLuna output transformers are custom-designed, wound in-house, and massive.
AC OFFSET KILLER - A PRIMALUNA EXCLUSIVE
AC Offset Killer is about goosebumps. PrimaLuna custom-winds our own massive toroidal power transformers that are low in hum and EMI. The PrimaLuna AC Offset Killer lowers transformer noise regardless of how bad your electricity is. This gives 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 amaze you.
ADAPTIVE AUTO BIAS
PrimaLuna's Adaptive AutoBias is a true, smart technology employing an array of sensors to monitor tubes and make adjustments seamlessly in real-time. 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.
Adaptive AutoBias also provides unparalleled flexibility by allowing the use of almost any tube on the market today.
POINT TO POINT WIRING W/ SWISS MADE WIRE
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.
SUPERQUIET LINE INPUTS
PrimaLuna's input selection uses premium quality sealed relays mounted in the rear. When an input is selected, that relay closes providing the best connection possible. All the other relays remain open. Noise and signals from other sources can't leak in. The signal path is now almost non-existent, so there are no wires to pick up noise.
SMARTWATTS - EXTENDED TUBE LIFE
Tube life is simply a matter of how hard you run the tubes. That's it. The only way to extend tube life is to run them as close to zero as you possibly can, making sure it is not so low you go into crossover distortion. The life of a tube will depend on two things: Plate and screen voltage.
