Beyerdynsmic Tx info needed

[pucho812]

I searched and search and can’t find data on the following. I couldn’t even find the magic decoder ring.

Tr/bv 372 309 792
It has a date code of 03 84 and has 7 pins in a circular thru-hole solder pin.

Saw that and seemed to not have that transformer in there.

I think beyer did some specials for different companies. I was trying to get a replacement mic transformer for an MCI JH428 & the number on the MCI's transformers doesn't correspond with anything on the beyer data sheet.

The pdf should get you close enough:
3: means studio grade transformer
72: isn´t in the list: custom mounting

3: two split bifilar primaries, the end of #1 and start of #2 is accessible as center tap
09: 1:9 ratio

The rest of the code isn´t described in the pdf.
