FS: Ribbon mic transformers: Lundahl LL2913
« on: November 18, 2018, 07:42:46 AM »


For sale,

2X Lundahl LL2913 Ribbon Microphone Transformers. Brand new. €60 each.
Specifications: https://www.lundahltransformers.com/wp-content/uploads/datasheets/2913.pdf


2X T-Bone RB 500 Ribbon Microphone Transformers. Used and taken from a working mic. €15 each.
They are the generic model also found under such names as Nady RSM-2, Apex 210 and ShinyBox 46. Note there are several variants of these transformers and their step up ratio is different. These two are no exception, they have different gain. They are a perfect fit for all kinds of ribbon mic experiments with good performance. I don't know the exact spec of these transformers.

Measurements.
Secondary static resistance: 30ohm (model B44305)
Secondary static resistance: 157,6ohm (model RSM-2)
Primary static resistance: below 0.3ohm for both - too low to reliably measure with my multi-meter.

EU sale preferred due to shipping convenience.
