Mechanical Dimensions

  • Size = Patt18x9/16 UC.
  • Width (W) = 1 3/4 inch(44mm).
  • Clamp Width (C) = 2 1/2 inch(64mm).
  • Depth (D) = 1 5/16 inch(33mm).
  • Height (H) = 1 7/16 inch(37mm).
  • Core (L) = 5/8 inch(16mm).
  • Fix Centres (F) = 2 1/8 inch(54mm).
  • Fix Size (FZ) = 3/16 inch(M3) .
  • Pin Length (P) = 1/4 inch(6mm).
  • Weight (WT) = To be added later.

  • A range of Coupling Transformers.
  • These are designed to be driven from the anode circuit of one valve and provide Grid Drive to one or two OutPut Valves in Power Amplifiers.
  • Alternative configurations and impedances are available to order.

  • Two section interleaved windings for low leakage inductance.
  • Low flux density for low distortion and low external magnetic fields.
  • Professional quality materials.
  • Compliant with current safety requirements.
  • Special versions made to order.
