For Sale U47 Mic

[lukas]

Little used U47 with EF86 Telefunken red dot(selected by factory), very good copy, sound samples available. Few scratches in mic aluminium body(black places). For set we have:
Power Supply, with Sommer cable, Mic and Mic basket everything for 900 USD plus shipping, and paypal fees.

Nice Mic,
but to be able to use an EF86 it means the circuit has to be quite different than an U47.
Do you know what circuit/schematic does this mic uses?

Thanks
