Phaethon

About the Phaethon

The Phaethon integrated amplifier is unique in many respects. It builds on the technologies of Ypsilon's separates and refines key details of the circuit even further.

The input uses a low-noise double triode, and the whole amplifier has just three gain stages. The power section uses a specially designed interstage transformer to couple the driver to the output stage.

The output stage uses semiconductors of the same polarity for both phases, in a 'balanced single-ended' configuration that combines a magical presentation with the power to drive most loudspeakers.

Tube and output stages have separate power supplies, with five power supply inductors for low-noise filtering, two power transformers and four signal transformers. All functions are remote controlled and shown on a high-resolution display that is legible from across the room.
