PrimaLuna EVO 100 Tube Power Amplifier

Overview

The PrimaLuna EVO 100 Tube Power Amplifier brings the warmth and dimensionality of classic vacuum tube sound into a beautifully built, real world package. Running a quartet of EL34 output tubes in push pull, it delivers 40 watts per channel in stereo and can be switched to mono for 82 watts, giving you a genuine upgrade path as your system grows. This is a power amp designed to be lived with, musical, reliable, and simple to own.

PrimaLuna builds the EVO 100 the way great tube amps should be built, with point to point wiring, custom super wide bandwidth output transformers, and a massive potted toroidal power transformer. That construction is the reason a modest wattage tube amp can deliver slam, extension, and quiet backgrounds that belie its rating. The result is a full, natural presentation with real weight at the bottom and air up top.

Owning a tube amp has never been easier thanks to Adaptive AutoBias and the Bad Tube Indicator. The amp constantly manages bias for consistent performance and long tube life, and if a tube fails it drops into protection mode and lights an LED at the offending tube. No soldering, no guesswork, no drama. Just swap and listen. At All Elite Audio we love pairing the EVO 100 with high efficiency loudspeakers for a captivating, room filling sound.

Key Features

• EL34 Push Pull Power. A quartet of EL34 output tubes in push pull delivers the rich, harmonically complete midrange that has made the EL34 a legend among tube listeners, with the tone and body that solid state rarely matches.
• Stereo or Mono Switchable. Run the EVO 100 as a stereo amp at 40 watts per channel, or switch to mono for 82 watts. Start with one, add a second later, and build a monoblock pair for more power and channel separation.
• Adaptive AutoBias. PrimaLuna's Adaptive AutoBias continuously manages tube bias for stable performance, lower distortion, and extended tube life. There is no manual biasing and no test meter required.
• Bad Tube Indicator. If a tube fails, the amp instantly enters protection mode to prevent damage and lights a red LED in front of the tube that needs replacing. Swap in a new tube and you are back to the music.
• Custom Wide Bandwidth Output Transformers. Output transformers determine how low the bass reaches and how high the top end extends. PrimaLuna winds its own massive units in house for bandwidth, slam, and extension you can hear.
• Potted Toroidal Power Transformer. A massive toroidal power transformer housed in metal and potted in non microphonic resin dramatically reduces magnetic and acoustic noise, protecting the windings and keeping backgrounds quiet.
• Point to Point Wiring. The EVO 100 is wired point to point by hand rather than on a circuit board, a construction choice associated with cleaner signal paths and long term reliability.
• Flexible Impedance Taps. Stereo 4, 8, and 16 ohm output taps and mono 2, 4, and 8 ohm taps let you match the amp to a wide range of loudspeakers for optimal power transfer.
