Description

PrimaLuna has pioneered numerous technologies to redefine tube amplification. From increased reliability and tube life all the way to their unique, signature sound. PrimaLuna was founded on the idea of eliminating tube maintenance. They do this by using a true and sophisticated Adaptive AutoBias system while running tubes at the minimum dissipation (power) and giving more slam and bandwidth through superior output transformer design.

They use 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. Then they add quality improvements, including Swiss-made wiring, , Takman resistors, DuRoch tinfoil capacitors. But PreimaLuna doesn;lt stop there. A subwoofer output, an AC offset killer, Triode/Ultra-Linear switching and incorporated their largest wide-bandwidth output transformers and largest Toroidal power transformers are a few other improvements built in.

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 go back to listening.

Power transformers generate two types of noise, magnetic and acoustic. That’s why toroidal power transformers are used in the very best audio products. Compared to standard transformers, 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 product, manufacturers will even house cheaper C-core and EI-core transformers in an outboard power supply box with an umbilical cable rather than upgrade to an expensive toroid. The increased cost is significant, but PrimaLuna doesn’t cut corners. 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.

Output transformers are the most important part of any tube amp. They determine how low the bass will reach and how high the top end goes. 250 watts of power will have no top and bottom extension if the output transformers don’t have the bandwidth. Prima Luna uses lower power to extend tube life, and bandwidth to preovide punch to the music. Since transformers are the most expensive components in an amplifier, many manufacturers try to save money by using ‘off the shelf’ units available on the market. PrimaLuna output transformers are custom-designed, wound in-house, and massive. One reason why no other brand sounds like a PrimaLuna.
