WTB: Cheap Ribbon Microphone Transformer for Experiment

[exp jst]

Hello, all; this is my first post.

I'm interested in doing some experimentation with an exotic design for a musical instrument pickup, and need a matching transformer that has characteristics amazingly like what one would find in a ribbon microphone. I've heard Edcor, Cinemag and Lundahl have (good, better, even better) units, and I imagine there are others... but, being currently underemployed, can't justify the bux for even the Edcor at this stage of the game.

If you're upgrading the transformer in a ribbon mike and are wondering just how long the discard will sit in your scrap box, perhaps you'd be willing to sell it to me? Thank you!
