Yet another Oatley 6J6 tube headphone amp. See an earlier posting for more details. A different chopping board for this mount and different beige boxes for connection points. The big improvement is the toroid power transformer. Where the earlier prototype hand an EI tranni which induced hum into the OPTs this toroid version is dead quiet.
An excellent HP amp to listen to. A pretty cct. brd. to show off. Good sounding and good looks make this a winner.
