LL1524 is an audio output transformer for balanced drive. The LL1524 is a 5-section output transformer. This results in a very low leakage inductance and thus excellent HF characteristics. The LL1524 is (like all C-core audio output transformers) ideally used with negative source impedance achieved using mixed feedback drive circuits. See separate paper for mixed feedback design principles.

Turns ratio: 1+1:1+1
