If it is a C12 or copy of a C12 you want to install Oliver's T14 copy in, no problem! Just make sure you wire it up polarity correct.

Is Telefunken Elektroakoustik still using the Haufe?  Can you get one from them?

Well its a Pape anyways, I wasn't sure if the 5743 had different components required to make it work for the circuit.

I managed to get a T14 from TAB yesterday, should have it inside a week.

Klaus,
I opened up the Pape today and the T5743 has 6 leads coming out of it as opposed to the 4 that appear on the T14 from AMI. Do you have any suggestions on how to integrate the T14 into the mic or is this something that will require more assistance than can be provided over the Internet?

Use an ohm meter and separate the leads: two of them most likely will be the primary coil (somewhere in the mid-to high 100 ohms).

The remaining four are likely from the two secondaries: each coil has an input and output lead. Series connection of the two secondaries will probably get you 200Ω output, parallel 50Ω.

I would run this transformer in the 200Ω output configuration, which would be similar to the series connection of a T14/1. (The AMI T14 secondary output is already wound for 200Ω, hence only two leads.)

Is it the same Haun Josephson uses in the 7 series mics?

Why would Josephson use a Haun CK-12 capsule in his mics when he's known for making precisely that type of capsule (also used in the Manley Gold)?
