P-RC-1P-RC-1Item ID: 003280Audio Choke - One Electron PRC-1, 5.5/22H for Shunt Feed SE Output
The PRC-1 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. It uses the same high quality M6 laminations as the UBT transfomers. Has two identical windings allowing series and parallel combinations. It is not recommended for use as a transformer. The table shows the maximum recommended load impedances when used as a shunt-feed choke. As with traditional class-A triode amplifiers, the driving impedance is about 1/2 the load impedance.

P-RC-3P-RC-3Item ID: 010037Audio Choke - One Electron 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. Since the plate can swing up to double the B+ value, a high output voltage can be attained with relatively low B+ values. Since the tube is presented with essentially an infinite load resistance at audio frequencies, the maximum gain is obtained and the tube is run in its most linear mode.

P-TUBT-1P-TUBT-1Item ID: 003628Transformer - One Electron, Output, 1600 to 16/8/4
The UBT-1 from One Electron is a low- impedance single-ended output transformer intended for parallel combinations of tubes running a B+ voltages of 250 to 325 volts, such as: two or three EL34s(triode connected), three 2A3s, two 300Bs, two 6AS7s, etc., as well as single sweep tubes run in 'enhanced-triode' mode, resulting in 10 to 15 watts of output power. The UBT-1s low impedance gives an exceptionally broad frequency range of 10Hz to over 75 KHz (at 1 watt). This transformer has been the basis for excellent-sounding single-ended amps, and is notable for its clean, detailed sound.

P-TUBT-3P-TUBT-3Item ID: 003630Transformer - One Electron, Output, 3000 to 4/8/16
The UBT-3 from One Electron is the same size and power (15 watts) as the UBT-1, but has a primary impedance suitable for single or paralleled tubes running at B+ voltages of 300 to 400 volts, such as: 2A3, WE 300B, 50, etc. The frequency response is from 10 Hz to over 60KHz(at 1 watt). The 3K primary impedance offers lower distortion at only slightly less power in designs using the commonly- specified 2.5K transformers. Quantity discounts available. 6.1 lbs.

P-TUBT-2P-TUBT-2Item ID: 003629Transformer - One Electron, Output, 4800 to 16/8/4
The UBT-2 from One Electron is the same size and power(15 watts) as the UBT-1, but has a higher primary impedance suitable for single tubes running at B+ voltages of 400 to 500 volts, such as: 50, WE 300B,etc. The trade-off of a higher impedance transformer is worse bandwith, but additional interleaving was added in the UBT-2 to extend the frequency range from 10Hz to over 55 KHz (at 1 watt). The UBT-2 has also been successfully used as a choke load for shunt-feed output stages. Plate supply voltages over 600 volts are not recommended. Quantity discounts available. 6.0lbs.

P-TBFT-1BP-TBFT-1BItem ID: 003583Transformer - One Electron, Power
The BFT-1B from One Electron> was designed to power a stereo amplifier using UBT-1s 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.
