Help with a part..


I need help locating specs including pinouts on a Beyer Dynamic mic input transformer. The only numbers on it are "TR/BV 372015006". It also says "Made in Germany" and has what appears to be a date code of 10/75.

The circiut board it is mounted on is labeled as an "input & eq module" and has "sonic services inc" etched in it also.

Any help with the transformer or information on the make of console this may have come out of would be appreciated.

Thanks in advance,

I have two Beyer datasheet scans on my hard drive, but found nothing remotely like that part number.

Double check it with a magnifier <g>.

I took off the tri-focals, put on the bi-focals and compensated for the glare...
I got out the magnifying glass and I checked with great care with both pair....

Those are the numbers......heh

Same problem I'm having, haven't found anything anywhere thus far....

It is on an input module, so I assume it's a mic and/or line transformer.
Nothing else on it other than what is described.
