Line Output Transformer for SE Solid State LL2734
The LL2734 is a line output transformer for SE solid state output circuits, based on the Neve LO1166A. The transformer consists of two coils, each coil consists of one primary winding (divided in two sections to reduce leakage inductance), one secondary winding and one feedback winding. The core is a special audio C-core of our own production.
