Has anyone accessed the amp in June's AudioeXpress designed by Satoru Kobayashi? Its a hybrid voltage driver circuit consisting of an IC phase inverter, a differential valve amplifier and a cathode follower with no negative feedback. 60 watts out and very stable with good specs. KT 88's seem to be expressing nice curves in triode mode. J.R.
