Description
The LBA-UJ 20 is the first official transformer design released by LBA. It's a step-up line transformer for coupling tube input stages to 600 Ohm studio line-level outputs. The UJ20 is housed in a MuMetal shielding can for superb rejection of external electro-magnetic, electro-static, and RF noise. The transformer core contains a high concentration of nickel, which facilitates a very wide bandwidth with low distortion. Its a step up transformer intended for converting 600 Ohm balanced line level (+4dBu) to unbalanced Hi-Z for tube input stages. Designed and crafted in a secret laboratory in North Collins, NY USA.
The UJ20 was the first transformer design offered by LBA. It's name draws from the guidance given to me by a transformer guru, my late Uncle Joe Marino and from its impedance ratio of 10k:20k. It was designed to be used as a high performance line-input transformer for tube stages. It converts balanced 600 Ohm line-level signals to a high impedance unbalanced 20k Ohms for vacuum tube input stages. As with all LBA input transformers, a magnetic shielding can and PC pins come standard.
