transformer
The 20C02 part of the Thordarson transformer is an audio transformer designed for use in tube amplifiers and other preamp applications. It is a single-ended, low-impedance transformer with larger primary and secondary windings than other similar models. It features a split-core design to eliminate magnetic flux leakage, and its primary winding is shielded to minimize EMI and noise. The 20C02 transformer also includes an air-gap between the core halves, which improves the durability of the transformer and reduces the risk of saturation when exposed to high-level input signals. This transformer is highly versatile and can be used in circuits requiring two to four output windings.
