LUNDAHL LL1544A audio transformer picture

This Lundhal LL1544A audio transformer is a general-purpose line input audio transformer that can be used for a wide range of applications. In particular, it can transform a balanced signal into an unbalanced one, or vice versa. This small transformer features two 3-section coils and Faraday shields. Its amorphous tape core combines high sensitivity for low-level signals with excellent capabilities for high-level signals. At low frequencies, phase response is excellent and resonance with a series capacitor is almost eliminated.
