I am trying to locate a replacement for a damaged coupling transformer
in an Ethernet transceiver (actually a DEC DELNI, but the same part is
used in ordinary transceivers too).

The part is in a 14 pin DIL epoxy package, and is marked as follows:

      16-18516-00 Rev. A1
       AC10135  yyww
         HIPOTTED 

(where 'yyww' is the date code).

There is no manufacturer's identification symbol.

I believe the part actually contains three transformers, used for 'receive
data', 'transmit data' and 'collision detect'.

If anybody can tell me who makes this part, where I can buy it, or where I
might find an equivalent, I would be most grateful. Please reply direct.

By the way, I HAVE contacted DEC.  They say "not available for sale".
