JT-115K-E transformer is designed for highest practical step-up ratio. Its secondary source impedance makes it ideal for use with low noise FET or vacuum tube input amplifiers. The primary is fully balanced and its leads may be reversed to invert polarity, if required. A 30dB magnetic shield package is standard.
