U-Clamp Frame Drop-Through Shroud with Feet
  • Page Updated 31 Jul 2017.
  • VTS12569 Ra corrected.
  • Single Ended Output Transformers for 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.
  • Transformers are initally designed for a particular valve and circuit but may be used with any valve with similar Anode resistance (Ra) and voltage rails.
  • Inductance is a nominal figure.
  • 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.
  • Gapped cores to define inductance.
  • Special versions made to order.
