I sell a BV107 microphone output transformer. It is in a perfect condition and was never used before. This transformer was used in the KM80 series (not the KM86), the U64 and in the SM69fet microphone. I have put this transformer into a U87 in the past and it made it sing. The U87 uses the same circuit, a S2436 or a 2N3819 directly into the transformer. But be aware, the U87 uses a BV13 in original, which has a different ratio, so this will be a compromise and I only did it, because there was no chance to find a BV13 at that time.

I have some of these transformers. Let me know, if you need more. If you need a stereo pair, I can search you a good match. For this I would wire the primaries in series and measure the inductance.

You will get an invoice. VAT is automatically added by Reverb inside of the EU, if you do not have a VAT registered business.
