Thanks Chuck! That is the most helpful diagram I've seen on the subject.

SO.... I bought that chassis before I gave it a thorough inspection. Turns out to be a 40-180, as far as I can tell in the pictures (7-tube set instead of 8). That having been said, all the transformers and tuning mechanism are identical, so I'm still spare-parts-sell-ahead. I also picked up Johnson's "Antique Radio Restoration Guide" on the strength of the reviews from Amazon. (I'll give it a mention as to how useful I found it to be. I suspect I'll still be making a break for my "theory of DC Circuits" and "Theory of Electronics" textbooks from college. S.o.B... I hope I still have 'em!
