UTC LS-30X line transformers (PAIR)

The auction is for a pair of UTC LS-30X, military grade, electrostatic shielded --- Does the same job as a Western Electric R-111C, but has even better specifications. They say 7 hz to 50 Khz.  Matching, coupling. Very good -74 dB hum specification, due to the inter winding shields. Priced at about the going rate for one unit here on Ebay, but this is for a pair. They spent their life so far in a shielded box on a wall in a temp. controlled studio.  Thanks for looking!   I have several pair of these and also some WE R-111C units that will be listed also.   The first pair has sold.  A  2nd pair is gone -  This listing is a for a third identical PAIR (one more pair left)
