PrimaLuna EVO100 Tube Phono Preamplifier
The starting point in designing the PrimaLuna EVO100 Tube Phono Preamplifier: to keep the controls and features as specific as possible – no special features for only a select number of users.
Straightforward the possibility to connect one turntable and for that connected turntable (read: 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.

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 our 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’s cooled, contact is restored and if nothing is broken, the preamp will repower and function properly.
- LIVE side of the AC input connector indicated by aluminium color screw.
