[Elecraft] Audio transformers needed

Looking for a pair of audio transformers, something in the range of 600 
to 2400 ohms impedance, 1:1 ratio (equal primary and secondary impedance).

These will be used to remove a ground-loop problem between my computer 
and other equipment.  I prefer something that will handle wide range 
audio, perhaps 30 to 15,000 Hz (wider is OK, but must be at least 40 Hz 
on the low end, and 12,000 Hz on the high end).

These are typically about 1" to 1 1/4" square and 1 1/2 to 2" deep, in a 
deep-drawn steel shell with 4 6-32 mounting studs.  I prefer a matched 
pair, but individual units are OK as long as they have approximately 
same configuration.

If you have something that may work, please let me know and perhaps I 
can arrange a trade or purchase. Removed from military or boat anchor 
equipment is OK, need not be new

Please reply off list, in other words, directly to one of my emails,  
shown below, to cut down on traffic to those not interested in this subject
