Prima Luna EVO 100 Tube Phono
The EVO 100 Tube Phono Preamplifier is their family’s newest and first member of affordable, high-quality tube phono products.
The designers and builders of the PrimaLuna equipment all have a long history in high-end audio.
They have shown with PrimaLuna that they can offer a range of affordable yet elegant audio instruments that can easily compete with today’s most expensive brands.
Their quality level will set the bar at a difficult height for other products to match.
The starting point in designing this model was to keep the controls and features as specific as possible—no special features for only a select number of users.
Straight forward the possibility to connect one turntable and for that connected turntable, cartridge make the possible adjustments as simple as possible.
Depending on that choice, an initial choice of MM or MC system allows further adjustments regarding the load, gain, and capacity in the case of MM.
High sound quality, simple ease of operation. This PrimaLuna EVO 100 Phono Tube Preamplifiers features:
Hand-made construction of a heavy-gauge, fully-vented steel chassis with a five coat finish, each coat hand-rubbed and polished, holding the finest point-to-point wiring, using workmanship that is normally only available at the highest price.
Premium parts like used in all their other models; wide bandwidth for great bass and extended highs
Ceramic tube sockets
Nichicon and DuRoch capacitors
5AR4 tube-rectifier-circuitry
gold-plated panel mounted RCA input and output jacks.
A 100% shielding Phono chassis where needed.
SoftStart™ circuit for extended life of sensitive components, plus a reduced chance of tube failure from thermal shock.
All PrimaLuna power transformers include the PTP™ (Power Transformer Protection) circuit.
When the power transformer overheats due to environmental circumstances, overloading or some problem in the unit,an internal thermal switch breaks the primary, allowing the unit to cool down before harm is done.
After it has cooled, contact is restored and if nothing is broken, the pre-amp will re-power and function properly.
