Lundahl LL2912 Ribbon Microphone Transformer

The Lundahl LL2912 is designed specifically as a ribbon microphone transformer. It uses a 1:37 turns ratio and is built around Lundahl’s proprietary high-mu amorphous strip core, making it a focused solution for sensitive microphone signal applications and precision audio components work.

This model is the flying lead version of the LL2911 microphone ribbon transformer, giving installers a practical connection format for compact microphone assemblies. Its small body measures 27 mm in length, excluding the leads, with a maximum diameter of 19.5 mm.

The LL2912 has a static primary resistance of 0.05 Ω and a static secondary resistance of 59 Ω. These values provide useful reference points for service work, installation checks, and electric measurements in microphone projects.

With a weight of only 17 g, the LL2912 is well suited to applications where low mass and compact dimensions matter. Its dedicated ribbon microphone design, amorphous strip core, and flying lead construction make it a specialized transformer for professional microphone building and repair.
