Don't tell me I stumped you all!!!!!!! I found an additional clue... I found a similar transformer on the web which referenced the manufacturer as DAL. Of course, I couldn't find that name anywhere on the web. So here is where I am at. I have a pulse transformer part number IPL-1032-22. I think the manufacturer is DAL. Has anyone out there heard of this company before? Thanks, Scott -- http://www.piclist.com#nomail Going offline? Don't AutoReply us! email listserv@mitvma.mit.edu with SET PICList DIGEST in the body
