The power stage features a pair of KT88 per channel connected in parallel and working, thanks to the particular elaboration of the output transformers, in single-ended ultra linear configuration. All the valves are rigorously selected and matched. Moreover, our long observation and in depth understanding of valves behavior has lead to the design of an original circuit which, through the control of the KT88 bias, ensures a real time compensation of the parameters affected by drift. This solution guarantees the best sound performances even after years.
