RE: triode wired KT88

"Now, let's record with a different microphone-- one that has two generator coils"

There is only one coil in a microphone.

Each end of that one coil (one piece of wire) is connected to the primary of a transformer in the mic body.

The secondary of that transformer is connected to the primary of the input transformer of the mic pre through a 2 conductor, shielded cable. Only the shield is grounded.

Neither end of the secondary of the mic transformer or the primary of the preamp input transformer is connected to ground.

The only thing that gets rejected by CMR is the hum and noise picked up in the cabling between the two units, not any of the audio signal.

None of the audio signal produced by the microphone coil moving in a magnetic field is rejected by the CMR of the balanced connection between the secondary of the mic transformer and the primary of the mic pre input transformer.

You do not seem to have an understanding of what CMR is or how it works.

You really need to forget what you think you know about this subject and read a book.

Good grief Dennis!
