Hi,
I'm trying to do a PSpice simulation of the KM84 (and later U87). Is there anyone who have the approximate inductance/resistance figure of the primary side of the BV107 output transformer? (And/or the U87 output transformer).
Or any other suggestion of an approximation of the primary side that can be used?

A question for Neumann:
When you develop new electronic for a microphone, do you use some kind of simulation tool? Just curios of the flow from idea to a working prototype.

Regards,
Mikael
