Beyerdynamic TR/BV 370 215 006 SUT [Expired]

This is a step-up transformer using Beyerdynamic TR/BV 370 215 006 transformers. Step-up ratio is 1:30, gain is +29.5 db. I purchased this from a previous owner intending to use it with a Denon DL-103, but plans changed, so I no longer need it. Rating it 8/10, only because it's had more than one owner. I accept payment thru Express Checkout.
