Unfortunately in the case of this microphone transformer we did not record the model number or specifications! This makes life a bit tough so the new owner will need to investigate the turns ratio/frequency response etc
98% sure this was another Harbuch product, we used to get a lot of transformer products from them (very reputable Australian transformer manufacturer and many of their products can be found in broadcast industry equipment manufactured in the 1980's ~ 1990's - Harbuch's "heydays")
UNIDENTIFIED - Audio Microphone Transformer
Probably of Harbuch Electronics origin (Sydney Australia) but not confirmed. Their website (try looking HERE, best of luck!) has become quite flakey since the original owners retired and no useful information on their website (no photographs or substantial technical information)
Intended for insertion into the body of your microphone
Flying leads 80mm length
DIMENSIONS:
14.5mm wide x 12.6mm deep x 11mm high
Beginning of one winding is indicated with a black dot (for phasing)
Very nice tight construction
TESTING:
My "proper" HP test equipment has now found new homes (isn't that always the way? Just when you think "I don't need that any longer" - you need it!)
So I cannot make reliable Z tests or plot a frequency response curve - that will be up to the new owner to sort out
However, I can make DC measurement tests - not really a great indication of transformer characteristics but some clues could be in these measurements (of course not frequency dependant though)
Yellow - White 49.4 Ohms DC
Black - Red 257.2 Ohms DC
