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. It features a paper bobbin. The frequency response is from 10 Hz to over 60 KHz(at 1 watt). The 3K Ω primary impedance offers lower distortion at only slightly less power in designs using the commonly - specified 2.5K Ω transformers. 6.1 lbs.

This is a good SE ouput transformer. I am using it with a DIY 300B SE amp and it is sonically sound. I only wish it looked a little better aesthetically.
