One Electron magnetic products have been designed to fill the need for high-quality yet affordable audio transformers and chokes that are not normally available elsewhere. This is why we have concentrated a bit more on the esoteric types. If you are interested in having One Electron add a new product, contact us, but keep in mind we only mass-produce our products. One Electron does not do custom transformer designs.
The datasheets for each type have specifications, application information, mechanical drawings, and suggested mounting holes.
Data sheets are in Adobe Acrobat format. 
The UBT series of single-ended output transformers are well-known for their clean, detailed sound, and broad bandwidth.

The PRC series of audio chokes are intended for shunt-feed single-ended output stages, but are also useful where a high quality filter choke is needed. Each has two windings that can be connected in series or parallel.

All One Electron power transformers are designed for critical audio applications and include an electrostatic shield between primary and secondary and a copper flux band to reduce stray magnetic fields. The international primary accomodates 100, 110, 120, 200, 220, 230 and 240 volt mains at 50 or 60 Hz.
