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.
Custom manufactured to replace most 6 and 7 tube sets of the early 1930s. Supplied with vertical mounting shells. Provides a seperate filament winding for audio output stages. Specifications Rating: 350-0-350 V, 70 or 90 mA (if 5 V winding is used with 2 A rectifier) Windings: 5 V, 3 A; 2.5 V, 7.5 A; 2.5 VCT, 3.5 A Mounting Centers:2 x 2.625" Weight: 4.2 lbs. Overall Height: 3.12"
100 watt replacement power transformer for Marshall. Good replacement for JMP and JCM800s for EL34! Built to vintage specs with exact interleave ratios and materials. Gives great classic sound. Great for upgrading later issue Marshall amps.
