This OPT measures 80mm(width) x 80mm(depth) x 100m(height)

  • 138H Primary inductance for excellent bass response.
  • Wide band width for excellent frequency response
  • We hand roll the transformers at our workshop.
  • The transformer are built up of 4 sections of Primary and three parallel connected Secondaries. The three secondaries cover the whole width of the bobbin, giving excellent coupling to the magnetic field (your music).
  • Ultra Linear taps are at 33% of the windings.
  • Fly leads are 400mm long to facilitate direct connection to tube sockets
  • We use South African made steel laminations.
  • We use South African manufactured copper wire
