The PrimaLuna brand of tube electronics was established in 2003 by Herman van den Dungen, who also runs Durob Audio, the high-end distributor from The Netherlands.

The PrimaLuna Floyd EVO 300 Hybrid Integrated Amplifier is a fine-tuned match of the  PrimaLuna tube pre-stage and Durob Audio’s Floyd Design Mosfet power stage.

Floyd Design has been Durob’s Solid State Design department for almost 20 years.  This department, headed by Jan de Groot, has been servicing, designing and modifying solidstate circuits since 2002! Jan has a long history and great experience with JFETs and Mosfets. After having been Service Manager from 1986 to 1995 for Luxman, Thorens, AirTight and Bowers & Wilkins in the Benelux region, he became responsible in 1995 for the design and production of Sphinx, a famous Dutch audio brand at the time. In 2002 Jan started to work for Durob Audio, participating in the real-world experience of distribution and servicing, repairing, modifying solid-state reference brands like Krell, Cello, Dartzeel, D’Agostino and more.

The Primaluna pre-stage uses the brand’s well known six piece 12AU7 configuration. The Floyd Mosfet power stage uses paired Linear Systems JFETs and 20N20/20P20 Mosfets resulting in a 2 x 100 Watt power rating at 8 Ohm. Where possible, they use hard wiring, and if PCBs are needed, they use the highest quality PCBs available (2.5mm thick instead of the standard 1.6mm), 105um (usually 35um) gold plated copper tracks.

The PrimaLuna pre-stage uses two power supplies (including two separate transformers), while the power stage comes with a single 500VA transformer. The starting point for all the power supplies is our AC Offset Killer circuit. The amplifier comes with six inputs (5 x Line RCA, 1 x HT) and outputs (tape out, stereo/mono sub, headphone and speakers, of course). It arrives with a fully shielded heavy-metal sub-chassis for the optional MM phono stage.
