Transformers & Chokes

One Electron

One Electron chokes and transformers are designed by John Atwood, to fill the need for high-quality yet affordable audio transformers and chokes that are not normally available elsewhere.
Choke - One Electron, Audio, PRC-3, 225H for Preamp Output
The PRC-3 audio choke from One Electron was designed as a plate load for the output of either a high quality line amplifier or a phono preamp.

Choke - One Electron, Audio, PRC-2, for Shunt Feed SE Output
The PRC-2 audio choke from One Electron was designed for shunt-feed single-ended output applications, but is also useful where quality inductive loads are needed or as high-quality filter chokes.

Transformer - One Electron, BFT-1B, Power
The BFT-1B from One Electron was designed to power a stereo amplifier using UBT-1's in each channel but will also power an 80 watt push-pull tube amplifier. The BFT-1B is slightly larger than earlier versions of the BFT-1, allowing lower flux density and cooler operation. The tapped high-voltage windings and three filament windings provide flexibility in design. An electrostatic shield between the primaries and secondaries reduces power-line noise coupling. The primary arrangements allows use on virtually any power grid in the world.
