Gardners MU7534 transformers info needed

[beatnik]

I came across a pair of these Gardners MU734 transformers as part of a lot i bought

I looked the web for datasheet but couldn't find anything

The label says matching transformer 50/200 ohm primary 100kohm secondary

I am guessing they are mic input transformers, but don't really know what they could be used for

Does anybody have information on them ?

I can give you the pin out , but it should be on the top of the transformer.  The data sheet doesn't really give any more information than you already have The ratio of this transformer isn't massively useful for recording gear, it's a bit high for most things.

could they be used as mic to grid input transformers ? was thinking they could be useful for a tube mic preamp

 

[Rob Flinn]

The ratio is about 1:22.  That is quite high for a mic amp.  You could try it out & let the rest of us know how it worked out .
