The new redesigned Concero 25 is our flagship of our smaller Prestige Series, a Direct Heated Tube Single Ended Monoblock amplifier.
The new design is designed using a blend of technologies used in our previous Concero 25 and Concero 65 amplifiers, modified to use the 845 tube.
As always we again endeavoured to produce a design that has all the sonic virtues of only the best of the best Single Ended amplifiers, but with absolutely none of their shortcomings.
Output stage
The output stage is based and designed around the 845 tube. The power supply,biasing circuit and output transformer is based on the tried and successful designs of the previous Concero 25 design.
Output is rated @ 20W, via a massive output transformer, with selectable 2, 4 and 8 ohm secondary winding selector.
The output transformer weighs more than many SET amplifier's total weight. The highest quality massive core of the output transformer used in the design, is mandatory for delivering true undistorted higher and lower bass, and driving any speaker through complex musical content. Many SET amplifiers get distortion when driving speakers with complex music,because of core saturation.Our output transformer can easily take 60W at 20Hz ,so at 25W intermodulation aftifacts are next to zero.
