Kora Galaxy triode stereo power amplifier 50w

The Galaxy is a 2 x 50w stereo (pushpull) amplifier that uses 6AS7G triodes as power tubes. It delivers a holographic soundstage and, above all, a musical and highly detailed presentation.

It features a parallel push-pull circuit topology. The 8 6AS7G triodes provide exceptional smoothness on vocals, with a fluid, refined and soaring character.

The circuit includes 6922 triode input tubes configured as a phase splitter and paired with Kora’s unique CSC circuit: a design that eliminates distortion by comparing the input and output signals without the drawbacks of classic negative feedback.
