After I poked around the net for a while, I found the NTE website with all
sorts of good info, including the pinouts of the 3041 I was looking for.
http://www.nteinc.com/specs/3000to3099/NTE3041.html
It's not quite the same as the 4N33 (not a Darlington pair on the output)
but will work fine for what I need.
Thanks to all who replied
