Output

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. It features a paper bobbin. The trade-off of a higher impedance transformer is worse bandwidth, but additional interleaving was added in the UBT-2 to extend the frequency range from 10 Hz 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. 6.0 lbs.

This has to be one of the best transformers made. I was originally experimenting with OTL amplifiers, which are known for their clarity and detailed sound. I decided, though, to go with something simpler, and so bought the UBT3. I was blown away! It sounded better than the several OTLs I experimented with! Clear, detailed, superb bass... what's not to like? I'd strongly recommend this to anyone wanting a output transformer for their amplifier.Great product! Thanks!
