PrimaLuna EVO 100 Tube Stereo / Monoblock Switchable Power Amplifier

PrimaLuna EVO 100 is a truly remarkable tube stereo power amplifier. It also has a switchable monoblock feature for you to add on another power amp as a monoblock.

PrimaLuna EVO 100 Tube Power Amplifier Features

 

Bad Tube Indicator

The PrimaLuna Adaptive AutoBias can automatically put your amplifier into a 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. Stereo

 

Custom Toroidal Power Transformer

The toroidal 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

Prima Luna uses 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 goose bumps. 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. Resulting in a sense of space. Texture. The resonance of an acoustic guitar or violin string that seems to trail on forever. The AC Offset Killer will amaze you.

Superquiet Line Inputs

PrimaLuna’s sealed relays are at the rear where you plug in your components. When an input is selected, that relay closes giving you the best connection possible. All the other relays are left open, so 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.  Make 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.

PrimaLuna runs their output tubes at a minimum dissipation without going into crossover distortion. When you look at our amps, they provide less power from each tube.
