- Page Updated 01 Jan 2011.
- 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.
