U-Clamp Frame Drop-Through Shroud with Feet

  • Page Updated 16 Jan 2010.

  • A range of Push-Pull Output Transformers for Valve Power Amplifiers.
  • Transformers are designed to match the valve data in our valve data page.
  • Alternative Ra or HT figures can be supplied. Call or Email to check feasability.
  • Various Mounting styles available.
  • Universal Push-Pull types can be used in Triode, 20% Ultra Linear and 43% Ultra Linear.
  • Some models are available in 'Magnetics Kits' with better prices for a set of magnetics.

  • Multi-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.
  • Impedance matched to specific valves and loudspeakers at rated RMS wattage.
  • Grain Orientated Thin Iron Cores.
  • Special versions made to order.
