XT-1 High-Impedance Transformer
9 in stock
The XT-1 is a sub-miniature audio input transformer that has a 15 to 1 turn ratio with an input impedance of 1,000 ohm and 30K ohm secondarily, making it ideally suited for matching low-impedance microphones to high-impedance audio preamplifiers such as the ones found in vacuum tube ham radio transmitters (Collins, Johnson, Drake, Heath, Hallicrafters, etc.) The XT-1 transformer is small enough to be mounted inside a microphone housing, some headsets, or mounted in a small metal box with appropriate connectors to mate with your microphone and transmitter.
Primary resistance is 2260 ohms with secondary set at 43 ohms.
