so nobody has re-duplicated the 5 pcbs?
no gerber / eagle files available?
a search returned no results on 4 of the 5
b205 (Shelving card) [wtf???]
ba182c
ba211 (Presence Card) [wtf???]
ba284
and obviously the fifth was once offered by 'fabio' at one point in time
ba283av (line amp)
besides (Linear's) version there is nothing im finding on a 'retro clone' of the 1073

maybe im just going about this all wrong?

One thing you might consider is searching through the many pultec threads on this board. What you could do is build the passive section of the EQ and stick an appropriate output transformer on there which will allow you to use your N72's for make up gain. I know this has been discussed in the past here. This would be considerably easier than trying to do the same thing with a 1073 style EQ and the circuit is simple enough that you could easily build it point to point. There is absolutely no reason to require a PCB to make a pultec EQ even if it is your first project, you'll be able to wire the eq section point to point really easily.

[quote author="soundguy"]so far as the sound of neve EQ's go, Ive personally felt for quite a long time now that the raving that goes on over neve EQ's is really raving over the amplifier stages driving the transformers in which ever EQ you happen to like, the EQ in and of itself isnt the most magical thing in the world. Very cool, sure, but the hype is sorta misplaced IMO. I think you could feed just about any EQ circuit into a 283AV style circuit and come away with a very "neve ish" sounding EQ so long as you use the appropriate output transfomormers.
